Introduce the `encrypted_data_source` class that wraps an existing data
source to read and decrypt data on the fly using block encryption. Also add
unit tests to verify correct decryption behavior.
NOTE: The wrapped source MUST read from offset 0, `encrypted_data_source` assumes it is

Adds a sibling type to encrypted file, a data_sink, that
will write a data stream in the same block format as a file
object would. Including end padding.
For making encrypted data sink writing less cumbersome.
Bulk transfer of EAR functionality. Includes all providers etc.
Could maybe break up into smaller blocks, but once it gets down to
the core of it, would require messing with code instead of just moving.
So this is it.
Note: KMIP support is disabled unless you happen to have the kmipc
SDK in your scylla dir.
Adds optional encryption of sstables and commitlog, using block
level file encryption. Provides key sourcing from various sources,
such as local files or popular KMS systems.
