The first Feature Flag we need is for Anoncreds.
The main reason is because we have an implementation of a uniffi warp for Anoncreds. But the Anoncreds version is already an old one.
Since we have we have a little time available to migrate to another warp of Anoncreds. We should have the option to enable or disable Anoncreds support.
