Issue:
[RPC] Add a getDelegates endpoint that points to minimal stake params or options
Implement a getDelegates RPC that supports this endpoint with following params:
`/chains/main/blocks/head/context/delegates?active=true&with_minimal_stake=true`

Taquito has a `getDelegates` endpoint but it is required to put a target address.


Either:
1. Implement a new getDelegates method (with a slightly different name) or,
2. Modify the existing getDelegates method
