Mate Szalay-Beko 451a4b06b1 HBASE-25263 Various improvements of column family encryption
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.

closes #2676
