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.

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.
* Raise an error when the value isn't a boolean or the expected string

* removes some cruft from the hbase-shell pom that appears to be from coping the hbase-server pom long ago
* puts the ruby scripts into the hbase-shell jar following the guide from jruby for packaging
* removes hard coding the location of the implementation scripts from our runtime
* removes hard coding the load path for the implementation from the test code (leaves hard coding the test code location)
* provides a work around for a name conflict between our shell and the ruby stdlib shell.
