Change subject: [master] KUDU-2181 Raft change config request for adding a
master
......................................................................
[master] KUDU-2181 Raft change config request for adding a master
This change:
- Adds hidden feature flag "--master_support_change_config" off by default
- RPC changes to add a master that initiates Raft config change and
responds asynchronously.
- RPC changes to report back member type(VOTER/NON_VOTER) of masters
- Removes the cached master_addresses in catalog manager as it's no longer
static.
- Updates and adds comments in MasterOptions such that it's used to fetch
master addresses only during master init time as masters can be added/removed
dynamically with this change.
- Updates ListMasters() to look at local Raft config instead of MasterOptions
as the masters can be added/removed dynamically.
If the new master can be caught up from the WAL then the master
gets promoted to VOTER else it remains as NON_VOTER without master tablet
copying support.
