Release Note

This patch changes the semantic around namespace create/delete/modify when coprocessor asks that the invocation be by-passed. Previous the by-pass was done silently -- the method would just return with no indication as to whether by-pass route had been taken or not. This patch adds throwing of a BypassCoprocessorException which is thrown if we have been asked to bypass a call.

The bypass facility has been in place since hbase 1.0.0 when namespace creation/deletion, etc.., was originally added in HBASE-8408 (HBASE-15071 is about addressing bypass handling in a general way)

Description

Add in a ClusterSchema Interface. It will have all API for all cluster manipulation; adding namespaces, tables, amending column families, etc. The idea is to gather up our mess and put it all behind a tidy API that all works the same way whatever you changing returning a Future to wait on and behind the scenes driving Procedures.

This patch does namespace operations first.
