NIFI-4866: Fixed HBase performance issue
HBase_1_1_2_ClientService performance dropped due to accessing HBase
admin upon every FlowFile transfer. Fixed that by getting master address
only once when the service is enabled and a connection is established.

> Components: Extensions
> Reporter: Koji Kawamura
> Assignee: Koji Kawamura
> Priority: Critical
>
> NIFI-4543 added
> "connection.getAdmin().getClusterStatus().getMaster().getHostAndPort()” call
> from HBase_1_1_2_ClientService.toTransitUri method in order to get HBase
> master address, which is called upon every FlowFile transfer and essentially
> doubles the traffic through the HBase connector.
> The performance of our PutHBaseJSON processor dropped to 1/3 after deploying
> NiFi 1.5.0.
> Those lines of code should be moved from toTransitUri to createConnection.
