NIFI-5062: Removed hbase-client dependecy from hbase bundle

[zenfenan]

Since the MockHBaseClientService and TestPutHBaseRecord extensively uses the Bytes from hbase-client class, I have created a new class with the same name and literally copied the necessary methods from the actual Bytes class to this one.

@zenfenan have you had a chance to run this against a live HBase cluster?

[zenfenan]

@MikeThomsen Yes. I tested it against my local one.

Ran build, it looks fine. Since everything that matters is in the HBase client, I feel confident with merging this.
