Summary:
Apps usually communicate with multiple hosts to support pops and data centres. The problem currently is that for each host we need a different config in the mock tab in flipper. If the host change due to failover then the mocking stops working. Added support to enter the URL without a host in the flipper. We then check if the Url from the actual network request contains the mock URL without a host.
We can change the hint on flipper UI to suggest either entering the complete URL or without the host to allow matching across multiple hosts.
Resolve:[3751](https://github.com/facebook/flipper/issues/3751)
Let me know if the approach looks good.

Summary:
Protobuf based APIs are becoming more common (i.e. gRPC) but are difficult to inspect. Unlike plain text data formats (JSON), Protobuf calls transmit binary data requiring the format to be known ahead of time, making ad-hoc inspection impossible. This PR allows for those format definitions (messages in protobuf terminology) to be transmitted from the client to the network inspector plugin. These definitions are then imported into ProtobufJS which enables the binary data transmitted to be inspected as easily as JSON data.
See Retrofit PR in https://github.com/facebook/flipper/pull/2084
## Changelog
* Add ProtobufJS library to network plugin
* New `ProtobufFormatter` UI in `RequestDetails`
* `ProtobufDefinitionsRepository` to cache and load protobuf defintions
* `addProtobufDefinitions` call in the Android network plugin

Manually uploaded as snapshot and full release, but with this setup still requires all sorts of manual setup, including GPG. Next PR will include automation for this.
CI here should also verify that I didn't split this diff up incorrectly.

Summary:
The Network Plugin does not properly handle network requests that return an empty body (because of the body actually being empty or because the network call returns something like a 404 status).
Also, the creation of mocks using the "Copy Highlighted" command when the original response returns an empty body is not handled properly.
## Fix
The Android plugin now returns a response when the body length is 0.
The client plugin creates a body containing an empty string instead of null when the body is empty.
## Changelog
Fix problem in Network Plugin when original call or mock has an empty body in the response.
Pull Request resolved: https://github.com/facebook/flipper/pull/1776
Test Plan:
The following screen output for the Network Plugin shows that the call is now being handled correctly. The fields for "status", "size" and "duration" are now populated.
Also, the mock calls are properly defined and shown in yellow.

Summary:
The default max body size for the OkHttpInterceptor that is reported to Flipper seems unreasonably small, as most images, graphql responses etc are bigger. Increased it to 1MB
Since the network plugin doesn't do any work if it is not explicitly enabled in Flipper, this should not lead to further performance regression / starvation.

Summary:
Images in the network plugin are rarely displayed in the network plugin, as it tries to use the public url to preview it. However, that won't if the endpoint is behind authentication, idempotent, etc. This diff changes the behavior to instead send the network body to flipper and use that to preview.

Summary:
It's common for responses to be completely missing in the network inspector. This is because they are larger than can be serialized in one go on some devices, so we drop all messages larger than 1MB.
This changes the android client to send large responses in individually serialized batches. This way we avoid running out of memory and can still send arbitrarily large payloads.
Changelog: Android network inspector can now handle responses large than 1MB.

Summary:
Previously, requests were passed to process first in an interceptor, and it is responsibility of an interceptor to process requests for responses. In FlipperOkhttpInterceptor, we did read data from request body before processing it. This caused a bug when the network process itself wants to also read that data, but the stream has been closed because the interceptor has just read. The fix is to report request body after we have triggered network call so that we can just drop request body if we cannot read.
This diff tries to bring back the same functionality while not cause the bug to occur by cloning the content to be read by Flipper and using the same one for the request.

Summary:
Original Issue: https://github.com/facebook/flipper/issues/993
The exception occurs when OkHttp and we try to read request body twice, while it can be only read once.
Hence, we will read request body after it is processed by OkHttp.
Tradeoff for this is requests on Flipper will not appear immediately after fired, but they will appear together with their responses.
There are ways we can get rid of the tradeoff. For example, as demonstrated in D21167308, OkHttp ^3.14.0 contains method `isOneShot`, which can be used to check if we can read request body more than once. Another example is to change server side to accept nullable variable so that we can send request body and others separately.

Summary:
Add logic on client side
# How it works (from the code)
1. Server side sends request url and method to response data and headers to client side
1.1. This will happen every time server update **any** mock response (add, edit, and remove)
2. Client stores those in map
3. For every network request,
3.1. Check if there is a matching url and method
3.2. If so, create a new response with the data and headers and drop the request
3.3. If not, proceed and send the request and wait for a response
`addNetworkInterceptor` is changed to `addInterceptor` to allow short-circuit and proceed without fetching anything. More info can be found at https://square.github.io/okhttp/interceptors/

- Connect an Android device
- Tap on Network plugin
- Click on the Mock button

Summary:
As previously reported in https://github.com/facebook/flipper/issues/457, I immediately started to see crashes with Flipper integrated due to large responses (e.g., >= 100MB). This will only write the first 100KB of the response or request body into `RequestInfo` objects.
## Changelog
- Limits request/response body in network request info to 100KB max.
Pull Request resolved: https://github.com/facebook/flipper/pull/617
Test Plan:
- Make a network request which has a response size of < 100kb, verify that it is visible in its entirety
- Make a network request w/ response size > 100kb, verify that it is truncated
- Ideally, use your application with the Network plugin running, and do not see OOMs
