Migrating role and roleTarget entities to the v2 core engine, allowing
v2 caching leverage and allow migrating agent to v2 that needs role
target in prior
After agent we should be able to pass twenty standard app totally though
workspace migration

## Role target assignation
Please note that role target have 3 creation entrypoints:
- Agent
- User workspace
- ApiKey

Refactored all 3 of them to pass through a new role-target.service.ts
that consumes the v2 under the hood.
