Summary: Adds UI to the select the plugin to export. It lists the plugins which has currently some data in the redux store and it also lists those plugins which has implemented `exportPersistedState` function, as it might happen that the redux store may not have the data for a plugin but it will still export the data by calling `exportPersistedState`, which will ping the mobile client to get the data at point while we export the flipper trace.

Summary: Adds close button to the dialog box which appears while exporting a flipper trace. To implement this I had to first see what is the bottle neck of the export process. The major bottle neck turned out to be the serialization step. So to make the export process interruptible, I have put in a call `await idler.idle()` which resolves when the main thread is idle. I have also added the tests for the idler.

Summary:
Non-final identifiers make code harder to understand.
This is particularly true for JavaScript where even the *type*
can change as a value gets reassigned later.
This enforces to use `const` whereever possible, but doesn't
"outlaw" `let`. Mixed destructuring is also still allowed.
Used `eslint --fix` to change all existing cases.

Summary:
Adds an argument to the headless Flipper to print the list of available plugins. Added `--list-plugins`.
Currently the startFlipper function is not scalable enough to add new arguments and its implementation. I am planning to tackle this with the list of Actions which will be closure. So adding a new argument with its implementation will be just appending a closure at the correct location in an array. Will work on that in the later diff stacked on the current one.

Summary:
Using `process.exit()` stops the node process without waiting for the event loop to finish, so when using async i/o, which is what happens when piped, if the output is buffered, the process can terminate before it finishes flushing the buffer.
This means you only get some of the output and the JSON is malformed.
This fixes it by calling `process.exit()` inside the flushed callback.

Summary:
1. Yargs doesn't like having the same option name as the given alias and will just silently skip those (like --metrics).
2. Having multiple ways of specifying the same argument is not a good practise.
I think we've been misusing `alias` as a way to have more JavaScript-y accessors, but ignoring that yargs already
converts `my-long-argument` to `myLongArgument` without having to expose this.
We haven't rolled out a version with the previous long arguments, so we should
still be able to change this without breaking stuff.

Summary:
This diff fetches the additional data by calling the hook added in each plugins when the headless tries to export metrics directly out of the store rather than from the trace.
I added `fetchMetadata` function which will be called while exporting the state as well as exporting the metrics. We do not need to fetch metadata in the case when the metrics are exported from the given trace.

`earlyExitActions`: Before the dispatcher is called on the store and will exit if the user arguments are one which are meant to terminate the process.
`exitActions`: This function will be called after the dispatcher is called and will exit if the user arguments are one which are meant to terminate the process.

Summary:
Added a promiseTimeout util so that we limit the time taken to export flipper plugin. I had received a feedback from the user stating that that the loader for the export stays for ages and never finishes. So this diff adds a timeout to the promise which is returned by `exportPersistedState` function. This function is currently implemented just by Layout inspector to fetch the entire view hierarchy. I suspect the the former mentioned bug may be due to the unresponsive client.
This diff also shows the plugin and the client information for which `exportPersistedState` timed out. Also this will hopefully solve the problem surfaced recently stating that the bug report gets stuck, the reason for which I suspect would be the same as the above mentioned reason, because we export flipper data when we create a bug report.

Summary:
This adds an optional exit strategy that reacts to the client disconnecting rather than a `SIGINT` which can be used for integration tests.
`MiddlewareAPI` is a subset of `Store` and required to work here.
Annoyingly, it's not quite clear to me why this does not work as part of an event loop cycle and requires a `setTimeout`. This doesn't have any negative effects and works in the same way that the SIGINT interruption works, but it's a bit of an eyesore.

Summary:
The headless version used to use `JSON.stringify` to serialize the output of `serializeStore` which basically transformed the store to a specific format which is serializable. But we have written the custom serialize function which cateres to the non serializable object types. Headless didn't use it, so thats why it exported Flipper trace in an unrecognizable format for the flipper.
I have also renamed `serializeStore` to `prepareToSerializeStore` so that the confusion doesn't occur in future. I have used an `exportStore` function in headless which exports the store to the `Promise<String>`

This diff does the following
- Support to export the entire view hierarchy for iOS
- Android is not supported yet
- This diff adds a call `getAllNodes` to the client side of iOS, which returns the entire view hierarchy
- Currently the search doesn't work on the imported layout plugin data. Also the imported layout plugin data doesn't expand the way it does when component is mounted, reason being the client passed to the plugin is not functional for the archived case
I will work on fixing the last points in the next diffs stacked on the current one.
For Android:
- Currently the export function will export whatever is currently displayed on the Flipper app, not the entire view hierarchy
Support for Android will also come up in later diffs.

Summary:
For the electron build, plugins are bundled with the app and loaded from there at launch. The headless version can't require from its binary, so plugins need to be required from another path.
This diff makes the path where bundled plugins are loaded from adjustable via an environment variable: `BUNDLED_PLUGIN_PATH`. If it's set, the plugins are loaded from this path, otherwise we default to the old behaviour of including them from `./defaultPlugins`.
For the headless version we expect the plugins to be in a folder called `plugins` next to the executable. This should later be configurable via an argument passed to the CLI.

Summary:
Adding `headless/index.js` This is the entry point to the headless version of Flipper.
This creates a redux store, and initializes the dispatchers. As all business logic (adb connections, etc.) are managed by dispatchers, this spins up a working version of Flipper, listening on our ports, allowing connections to devices.
For APIs not available in node.js, we are adding polyfills. `WebSocket` is used by redux-devtools, `fetch` is used in a couple of places throughout the application. These polyfills are added to the global namespace, so the app can run the same as in the browser.
