Adds region state check on hbck2 assigns/unassigns. Returns pid of -1
if in inappropriate state with logging explaination which suggests
passing override if operator wants to assign/unassign anyways. Here
is an example of what happens now if hbck2 tries an unassign and
Region already unassigned:

Previous it would just create the unassign anyways. Now must pass override
to queue the procedure regardless. Safer.

javadoc on assigns/unassigns. Minor refactor in assigns/unassigns to cater to
case where procedure may come back null (if override not set and fails state checks).

checkstyle cleanups.
Clarifying javadoc on how there is no state checking when bulk assigns creating/enabling
tables.
createOneAssignProcedure and createOneUnassignProcedure now handle exceptions which now
can be thrown if no override and region state is not appropriate.
Aggregation of createAssignProcedure and createUnassignProcedure instances adding in
region state check invoked if override is NOT set.

Change to setProcedure so it returns passed proc as result instead of void

Mark RegionInfo#UNDEFINED IA.Private and deprecated;
it is for internal use only and likely to be removed in hbase4.
Move MutableRegionInfo out of RegionInfoBuilder and have it as a
stanadlone task; a nice-to-have.

* HBASE-24806 Small Updates to Functionality of Shell IRB Workspace
- Move exception handler from Shell::Shell#eval_io to new method,
Shell::Shell#exception_handler
- Add unit tests for Shell::Shell#exception_handler
- Change Shell::Shell#eval_io to no longer raise SystemExit when any error is
seen and update unit test
- Update ruby test runner to catch SystemExit and fail to avoid tests that
cause the test runner to incorrectly exit successfully
- Add Hbase::Loader module to find ruby scripts in the $LOAD_PATH and classpath
using JRuby's loader.
- In hbase-shell, install IRB commands before exporting HBase commands. The
HBase commands will override the IRB commands, and no warning will be
printed.
* Remove unused variables from shell_test

* HBASE-24874 Fix hbase-shell access to ModifiableTableDescriptor methods
- Fix hbase-shell access in JDK 11 for calls to
TableDescriptorBuilder.toCoprocessorDescriptor and
ModifiableTableDescriptor.toStringTableAttributes.
- Allow coprocessors to be specified using a Ruby hash in the hbase-shell alter
command and replace usage in the help text. The previous String overload of
the alter command will continue to work and is still covered by a unit test,
but will no longer be suggested in the alter command help.
* Update patch
- Add warning over toCoprocessorDescriptor noting the usage by hbase-shell
- Add constants to hbase_constants for coprocessor specification
- Document usage of ModifiableTableDescriptor.toStringTableAttributes
* Convert comment over toCoprocessorDescriptor into docstring

* add `testMergeEmptyRegions` to explicitly cover different

* fix bug where merging a 0-size region is skipped due to large
neighbor.
