HBASE-21213 [hbck2] bypass leaves behind state in RegionStates when assign/unassign
Adds override to assigns and unassigns. Changes bypass 'force'
to align calling the param 'override' instead.

Adds recursive to 'bypass', a means of calling bypass on
parent and its subprocedures (usually bypass works on
leaf nodes rippling the bypass up to parent -- recursive
has us work in the opposite direction): EXPERIMENTAL.

bypass on an assign/unassign leaves region in RIT and the
RegionStateNode loaded with the bypassed procedure. First
implementation had assign/unassign cleanup leftover state.
Second implementation, on feedback, keeps the state in place
as a fence against other Procedures assuming the region entity,
and instead adds an 'override' function that hbck2 can set on
assigns/unassigns to override the fencing.

Note that the below also converts ProcedureExceptions that
come out of the Pv2 system into DoNotRetryIOEs. It is a
little awkward because DNRIOE is in client-module, not
in procedure module. Previous, we'd just keep retrying
the bypass, etc.

M hbase-procedure/src/main/java/org/apache/hadoop/hbase/procedure2/Procedure.java
 Have bypass take an environment like all other methods so subclasses.
 Fix javadoc issues.

M hbase-procedure/src/main/java/org/apache/hadoop/hbase/procedure2/ProcedureExecutor.java
 Javadoc issues. Pass environment when we invoke bypass.

M hbase-server/src/main/java/org/apache/hadoop/hbase/master/HMaster.java
 Rename waitUntilNamespace... etc. to align with how these method types
 are named elsehwere .. i.e. waitFor rather than waitUntil..

M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/RegionTransitionProcedure.java
 Cleanup message we emit when we find an exisitng procedure working
 against this entity.
 Add support for a force function which allows Assigns/Unassigns force
 ownership of the Region entity.

A hbase-server/src/test/java/org/apache/hadoop/hbase/master/assignment/TestRegionBypass.java
 Test bypass and force.

M hbase-shell/src/main/ruby/shell/commands/list_procedures.rb
 Minor cleanup of the json output... do iso8601 timestamps.
