* Update the infludb broker to not need a server so that it'll work on non-data node servers
* Update messaging broker to keep track of connect urls for replicas
This commit refactors the raft package to more loosely couple the individual parts. The clock is now broken into
an interface that signals individual actions in the log. The transport has been mocked to allow more control over
the log tests. The handler's log has been mocked to separate its testing from the log itself.
