Tyr Backbone Creation

# Changes:

## Patchwork
- Renamed FreedomExecutor to ExecutorProvider and moved the class to the provider package.
- Created an SQL Registry to prevent dependencies on Datura for SQL data. SQL is returned through an Optional, in the event that there is no SQL service registered.
- Created SQLResult, a generic ORM for ResultSets to avoid working directly with SQL data.

## Tyr
- Created Identity, which houses a username and related secret key.
- Created SQLEntry which stores the information from the Identity class into an SQL table called sessionData.
- Created TOTP, a simple static class that allows easy access to TimeBasedOneTimePasswordUtils class.
- Created OAuth2 which houses identities and performs the appropriate credential validations (incomplete)
