Remove Goose

[rob05c]

Traffic Ops uses Goose for database migration. Goose is unmaintained, and has been for years. We need to move to a maintained db migration tool. For security, bug fixes, ease of use, etc.

The most difficult part of this will be removing the 1 Go migration we have, which won't be supported by a generic SQL migration tool. It will need to be converted to real SQL. Alternatively, if we "squash" the migrations into the default seeds in a release, including that migration, that may solve the problem (or it may be equally difficult to squash).

The migrations were recently squashed, so the one Go migration we had is now gone.

Note: as of #5699, we are using a maintained fork of goose. However, it doesn't seem to be a very popular fork, so we'd probably still prefer to move off of goose altogether for something more popular.
