Automated socket reconnect

[lugehorsam]

• Adds retry and cancellation token to the actual connect operation
• Adds connect with retry if the socket disconnects due to an IOException.
• Defaults autoReconnect to false. The reason I did this is in case users have existing code doing socket reconnects. If they upgrade and forgot to change a true parameter, they would be "double reconnecting" in the case of disconnects.

Are there any known issues that need to be addressed before this is ready to merge in? I'd like to use this instead of implementing my own socket keep-alive logic.

@LobsterUberlord The socket code was refactored earlier in the week so I'll need to rework this code to support socket-based reconnects: 6811339

This code can't be rebased and merged in its current form. If you're interested to introduce a pull request to bring this logic into the SDK I'd be happy to review it for you. 🙏
