Description

I'd like to remove our use of master/slave terminology in favor of something that doesn't carry a racially charged meaning.

As a side effect I'd also like to pick names that carry better meaning of how things work within Accumulo.

In the case of a single cluster, I'd like to

• Change the Master role to Coordinator
• Change the associated master server package to coordinator
• Change the master configuration file to be named coordinators
• Change the slaves configuration file to be named tservers

In the case of the in-progress replication work I'd like to change terminology:

• use Primary Cluster in place of Master Cluster
• use Replica Clusters in place of Slave Clusters

I intend to do this in all active branches in a way that maintains compatibility of existing configuration files and serialized actions (i.e. fate operations) within their major branch. In the current unreleased major branch I expect upgrading will require user action (e.g. renaming configuration files).
