Crypto: Modularise the interaction with crypto primitives
This patch creates an engine layer inside the service to
modularise all the operations that involve cryptography
primitives.
It also updates the service documentation, fixes some minor
issues in the NS crypto interface test suite, and updates the
manifest file for the crypto service removing outdated functions.
