Goldiloader is great, but has several issues with has_many :through relations:

* https://github.com/salsify/goldiloader/issues/12
* https://github.com/salsify/goldiloader/issues/14
* https://github.com/salsify/goldiloader/issues/18

Rather than try to figure out which applies in each case, we should just do the
drudge work of manually disabling autoloading for all relations of this type. We
can always use regular preloading for specific cases, but this way we avoid
generating invalid queries through Goldiloader's magic.

Goldiloader (https://github.com/salsify/goldiloader) can eager load
associations automatically. This removes the need for adding "includes"
calls in a variety of different places. This also comes with the added
benefit of not having to eager load data if it's not used.

The TIMESTAMP data type is used for values that contain both date and
time parts. TIMESTAMP has a range of '1970-01-01 00:00:01' UTC to
'2038-01-19 03:14:07' UTC.

A Forever lib class was included to handle future dates for PostgreSQL
and MySQL, also changes were made to DeployToken to enforce Forever.date

Also removes extra conditional from JwtController

- Adds a default on expires_at datetime
- Modifies deploy tokens views to handle default expires at value
- Use datetime_with_timezone where possible
- Remove unused scopes

Also, fixes broken specs

We use controller actions to pass a newly created token and errors

Also:
- Changes scopes from serializer to use boolean columns
- Fixes broken specs

- Remove extra method for authorize_admin_project
- Ensure project presence
- Rename 'read_repo' to 'read_repository' to be more verbose

- When using 'read_repo' password and project are sent, so we used both
  of them to fetch for the token
- When using 'read_registry' only the password is sent, so we only use
  that for fetching the token

Also fixes spec failures on presenter and docs
