So, a couple of comments here:

1. Linking snapshot dependencies in hedera-services is a risk. This has already bitten me.
2. The actual code of the library already has a mock (really, it is more like a fake) implementation.
3. Respecting packages and library names can reduce future rework.
4. Maybe a better place for the fake is hedera-cryptography?

@MiroslavGatsanoga can you have another look to the ParticipantDirectory, we changed id from Integer to Long just now

LGTM! Thanks @MiroslavGatsanoga
