It has no meaning to stay in election state when the primary master is
known. Also, it causes problems as the elected primary master will soon
start sending packets we don't expect while election is running.

handler/election.py:
- Receiving announcePrimary is enough to exit election immediately, so
  reach election end condition (both sets must be empty)
- Receiving answerPrimary with a known primary is enough to exit election
  immediately (don't attempt to connect to to primary master).
app.py:
- Apply PrimaryHandler while iterating over connections when the primary
  master connection is found, rather than once all other connections are
  closed.
- If no primary master connection was found, start establishing one.
handlers/secondary.py:
- Handle connectionCompleted event as we might only reach primary master
  once with this handler if connection was not established during election.
- Likewise, handle connectionFailed event, and treat it as a primary
  failure.
- Stop ignoring answerPrimary packets, instead check that advertised
  primary master is the expected one and request node identification.

This makes garbage collector delay logging module deletion upon interpreter
shutdown, preventing occasional tracebacks from epoll thread.

This packet was misnamed as it's an answer.

Almost any use of packet was to retreive the msg_id of the request and pass it to answer().
In storage's replicator, critical TIDs are indexed with UUID instead of remote connection ID (full replicator review required).
In admin node, expected answers are still queued with the msg_id but it seems useless as no concurrent queries should happen.

The connection now store the last generated remote ID. If no msg_id is supplied to answer(), the last received ID will be used.

This condition is always true as the primary_node was found by UUID.

This fixes strange epoll results (yielding unknown file descriptors).
There is no explanation as of why it worked in 64bits until now.

Consequence of previous commit, to preserve code clarity.

This state was only internal to master node, and was not even
consistently handled in master (only the first election was done in that
state).
changeClusterState was never called with that state as parameter.
Finally, remove this state from protocol as it's not used any longer.

So that unknown nodes, to which no connection succeed for the current election, are dropped from election process.
