Verify-fail-count for users (#18)

* feat: Ban user on 3 failed verification attempts

- created user schema
- ban handler

* [Fix]:Use !verify only in #verify channel

- blocked DM
- removed unnecessary return statements

* [Fix]: Check if "user" exists to tackle rejoin

* [Fix]: user.existsInUsers was never getting called without await.

* [Fix]: Made husky work(hopefully).

* [Fix]: Minor change
