Add support for restarting a connection

[vkottler]

This would be huge.

This is required to implement something like: #53. Ideally some kinds of connections just try to be "sticky" and continuously attempt to re-connect (when connect -> disconnect occurs, not spamming connection attempts when starting up).

The OS should handle exponential back-off under the hood on its own.

Implemented on: #144.
