OPSAPS-66217: ZooKeeper-less connection support for HBase clients

Clients are required to connect to ZooKeeper to find the location of the RegionServer that hosts the meta table region. Site configuration provides the client a list of ZooKeeper quorum peers and the client uses an embedded ZooKeeper client to query meta location.

New configuration settings are introduced in Cloudera Manager that provide a list of well-known master and backup master locations, and with this information the client can contact any of the master processes directly. Any master in either active or passive state tracks meta location and responds to requests for it with its cached last known location. This removes the dependency of ZooKeeper client from HBase clients and also simplifies the firewall configuration to access HBase.
