Summary:
Never really liked this code. Before this change, calls to connect were blocking.
Because of this, we had to make use of promises and a bit of really not that good-looking code.
So, this change makes connect non-blocking meaning that we make full use of our event handler.
These changes contain:
- CSR is not getting generated after each failed attempt.
- Connect is no longer blocking.
- Do not report events via the handler when explicitly disconnecting.

Summary:
This change mainly removes the connection timeout period as it may introduce a race condition in which slow server connections get terminated potentially creating connection loops.
Also, suspend and wait for all operations to complete once a socket is disconnected.

Summary:
A few changes that should make our connect/disconnect more robust:
* Certificate provider handler should be set directly to and managed by the policy.
* Instantiate the socket once, synchronously on the connect method. Explicit deallocation once, synchronously on the disconnect method.
* Clear handlers on disconnect after clearing the delegate.
* Wait for the operation queue to drain before returning.

Summary:
Flipper doesn really use library specific exceptions throughout, and that's OK.
Introducing SSLException as a replacement for the existing Folly Async Socket SSL exception.
This exception originally thrown by rsocket. Because we had rsocket and websockets using the same code, websockets were creating and throwing this same exception.
With rsocket gone, we can fully replace the usage of that exception. This is also needed as to decouple Flipper from folly async components.

Summary:
This diff ensures that all operations on the socket are put into a serial background queue, including delegate callbacks.
All operations are executed asynchronously except disconnect, which is made synchronous as to guarantee no resources are accessed after the call.

Summary:
This change removes ourselves as a delegate before closing.
SocketRocket uses its own internal async queue to perform most operations.
After a disconnect, we don't expect to receive any more delegate calls as the handlers may contain references which may have become invalid.
So, removing ourselves as delegates will ensure that we don't get called after a disconnect.
For sanity, we are also taking a copy of the message handler instead of a reference to it.

Summary:
Trigger a manual disconnect on deallocation. This was done automatically for us when the underlying socket gets released. But, this gives a bit more visibility and control onto exactly when this is going to take place.
Additionally, do not clear the message handler when a message is received.
It is not required as sendExpectResponse is one time called only used for certificate exchange. If this takes place again, a new handler will be set anyway.

Summary:
This change makes WebSockets the default for Flipper on iOS.
Having said that, we are introducing some logic to deal with clients connecting to older Flipper Desktop versions.
The mobile client will first attempt to connect via WebSocket with the Desktop. This connection can either be secure or insecure. If that fails, it will attempt to connect via RSocket.
Connection failure logic:
The mobile client will attempt to connect up-to 3 times via a WebSocket. If it fails to connect, then the socket provider is switched to RSocket.
As before, the mobile client will attempt to connect up-to 3 times via a RSocket. If it fails to connect, then the socket provider is switched back to WebSocket.
Process repeats until a successful connection is established.
Some logs that can be seen from iOS:

About SocketRocket and Cocoapods
A decision had to be made about whether to define different sub-specs, one for RSocket and another for SocketRocket.
I've opted to keep the podspec as is because:
- Keeps pod consumption as is.
- Makes easier to switch implementations using GK.
- There's no intention to keep RSocket going into the future. So, there's no point in creating a sub-spec only to remove it in the future.
- SocketRocket is a relatively small library so is not contributing to a significant increase in binary size.
If, as reviewer, you consider a subspec makes more sense, then feel free to reach out to discuss.
