Alexander Shraer updated ZOOKEEPER-1411:
----------------------------------------
Description:
Currently every server has a different static configuration file. This patch
distinguishes between dynamic parameters, which are now in a separate "dynamic
configuration file", and static parameters which are in the usual file. The
config file points to the dynamic config file by specifying
"dynamicConfigFile=...". In the first stage (this patch), all cluster
membership definitions are in the dynamic config file, but in the future
additional parameters may be moved to the dynamic file.
Backward compatibility makes sure that you can still use a single config file
if you'd like. Only when the config is changed (once ZK-107 is in) a dynamic
file is automatically created and the necessary parameters are moved to it.
This patch also moves all membership parsing and management into the
QuorumVerifier classes, and removes QuorumPeer.quorumPeers.
The cluster membership is contained in QuorumPeer.quorumVerifier.
QuorumVerifier was expanded and now has methods such as getAllMembers(),
getVotingMembers(), getObservingMembers().

Currently every server has a different configuration file. With this patch, we
will have all cluster membership definitions in a single file, and every sever
can have a copy of this file.
Summary: Consolidate membership management, distinguish between static
and dynamic configuration parameters (was: Consolidate membership management
and add client port information)
