The code starting at `ZKUtil.dump(ZKWatcher)` is a small mess – it has cyclic dependencies woven
through itself, `ZKWatcher` and `RecoverableZooKeeper`. It also initializes a static variable in
`ZKUtil` through the factory for `RecoverableZooKeeper` instances. Let's decouple and clean it
up.

* refactors how we handle running the passed in initialization script to make use of IRB sessions
directly instead of reimplementing things ourselves
* simplify how we initialize our IRB config
* insert a shim for capturing exit codes passed via user calls to exit
* make use of user provided exit code unless we're reading stdin in interactive mode
This changes the exit code of the shell
* a 0 return code, or no return code, passed to a call to exit from stdin in non-interactive mode
will now exit cleanly. in prior versions this would have exitted with an error and non-zero exit
code.
* for other combinations of passing in an initilization script or reading from stdin with using the
non-interactive flag, the exit code being 0 or non-0 should now line up with releases prior to
2.4.z, which is a change in behavior compared to 2.4.z.

* HBASE-25497 move_namespaces_rsgroup should change hbase.rsgroup.name config in NamespaceDescriptor
Signed-off-by: Zheng Wang <wangzheng@apache.org>
(cherry picked from commit 9e9bec24d2)
This PR is a follow-up of HBASE-25181 (#2539), where several issues were
discussed on the PR:
1. Currently we use PBKDF2WithHmacSHA1 key generation algorithm to generate a
secret key for HFile / WalFile encryption, when the user is defining a string
encryption key in the hbase shell. This algorithm is not secure enough and
not allowed in certain environments (e.g. on FIPS compliant clusters). We are
changing it to PBKDF2WithHmacSHA384. It will not break backward-compatibility,
as even the tables created by the shell using the new algorithm will be able
to load (e.g. during bulkload / replication) the HFiles serialized with the
key generated by an old algorithm, as the HFiles themselves already contain
the key necessary for their decryption.
Smaller issues fixed by this commit:
2. Improve the documentation e.g. with the changes introduced by HBASE-25181
and also by some points discussed on the Jira ticket of HBASE-25263.
3. In EncryptionUtil.createEncryptionContext the various encryption config
checks should throw IllegalStateExceptions instead of RuntimeExceptions.
4. Test cases in TestEncryptionTest.java should be broken down into smaller
tests.
5. TestEncryptionDisabled.java should use ExpectedException JUnit rule to
validate exceptions.

Expose an argument on the `count` command which is passed to the
`setCacheBlocks` method on the Scan which the count command uses.
This is a quick and dirty approach to read all of the blocks for a table
into the block cache.

* 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-11686 Shell code should create a binding / irb workspace instead of polluting the root namespace
- Refactor Shell.export_commands to define commands using ruby lambdas.
Additionally, this change stores a reference to shell_inst in scope so that
we no longer need to assume the existance of the variable @shell.
- Add logic to Shell class for constructing an IRB workspace with its own
binding and non-global receiver. This workspace is loaded with all HBase and
IRB commands.
- Create new method on Shell for evaluating input from an arbitrary IO instance
within the created IRB workspace. This is based on work by Hsieh that was
previously in bin/hirb.rb. This method is more generic and more testable.
This single pattern can be used for both executing files and reading from
stdin, therefore reducing complexity.
- Move special 'help' and 'tools' command definitions to shell.rb. These
commands are tightly linked with an instance of the shell, so it is easiest
to have them defined together.
- Remove all global includes of HBaseConstants from ruby test files. Before
this change, tests were loading these constants into the top level, which
could cause tests to pass that should really fail.
- Try to reduce the number of places that constants are included. I think it's
best to reference each ruby constant's full name, but where that would cause
a big diff I instead moved the include to the innermost Module or Class.
- Update docs and comments
- Remove unneccessary includes
- Add shell --top-level-cmds compatibility flag. Since this PR removes all the
HBase symbols from the top-level receiver (ie. main Object), it is possible
(albeit unlikely) that this will break operator scripts. This flag will
export all the commands at the top-level like the shell previously did.
* HBASE-11686 Light refactoring with added unit tests
- Fixes some constants references by admin test 2
- Install HBase commands as singleton methods on recevier instances so that
multiple receivers may exist.
- Rename new flag from --top-level-cmds to --top-level-defs to be more
semantically accurate.
- Create new helper method Shell::Shell#export_all to install @hbase, @shell,
constants, and all hbase commands to a target receiver. As a result, the
HBaseReceiver became very simple and could be moved to shell.rb.
- Add unit tests for Shell::Shell#eval_io and Shell::Shell#export_all
- Add @hbase and @shell to hbase-shell IRB workspace
- Fix robocop issues within patch
