Summary:
RSocket plays nicely with Folly and OpenSSL.
Flipper WebSocket-client uses SocketRocket which instead relies on Apple's NSInputStream and NSOutputStream types.
SSL options can be set to secure the communication in both.
Unfortunately, Apple APIs are a bit limited on the supported cryptographic formats it can accept as arguments.
SSL options require the client certificate to be set in PKCS #12 format, contrary to the existing PEM format used by RSocket.
This change adds a method to the ConnectionContext which converts and saves the client certificate in PKCS #12 format.
The method is always expected to succeed as it will only be called once a valid client certificate is available. An unlikely failure will raise an exception.
