CORE-2436 Extend manifest scanning to capture custom crypto classes. (#119)

* CORE-2436  Extend manifest scanning to capture custom crypto classes.

Scan for cpks DigestAlgorithmFactory

Scan classes implementing net.corda.v5.cipher.suite.DigestAlgorithmFactory in a cpk
and add them to the cpk's manifest.

Part of POC (see Jira) to demonstrate we can define and instantiate custom crypto.

* CORE-2436  Bump API version as scanning for custom crypto classes is a breaking API change.

* CORE-2436  Rename crypto classes manifest entry

Address PR comment and rename custom crypto to digest-algorithm-factory
where appropriate.
