Kaveh Vahedipour 7e816db51e Bug fix/agency restart enhancements (#3619) 
* Removed unused active(...) method in Agent
* Inception's restart from persistence allows peer with empty active RAFT list to join
* Agency's UUID is persisted outside of the database comparable to coordinator and db server action.
* Publicized Methods to UUID stuff in ServerState
* Inception method documentation
* added --agency.disaster-recovery-id to allow for specification of known former agency id. this is a very dangerous option potentially.
* Delete a unused methods.
* separate _id and _recoveryId
* populating active list with entire pool
* Improve logging.
* reject gossip from unknown agent, if pool is complete

Max Neunhöffer d86f27bd19 Bug fix/agency leader timeouts (#3373) 
* Send out empty heartbeats regardless of non-empty AppendEntriesRPC.
* Also improve logging:
  Note if a log in the empty heartbeat sending takes > 0.01 s.
  Clearly mark places where a leader resigns in logging.
  Log if no empty heartbeat is sent out.
* Make leader more tolerant w.r.t. incoming AppendEntriesRPC responses.
* Add debug logging for _lastAcked and challengeLeadership.
* Remove some unused code. Do not count ourselves in challengeLeadership.
* Removal of entire activation/deactivation mechanisms in agency
* TRI_microtime up to c++11
* added term to response to sendAppendEntries.
