Remove upgrades

## Remove upgrades

Upgrades are complicated to manage, unnecessary, and pointless.  Migrations can be used for data as well as structure.

### Acceptance Criteria
1. All code for creating and running upgrades is removed.
1. ~~`migrations:run` now accepts `--drop-tables` flag which has the same behavior as `upgrade:run --drop-tables`~~
1. `install:run` replaces `upgrade:run --drop-tables`.
1. `migrations:run` now automatically installs the DbStructure and DbData files and runs the install script if the database is not installed.
1. Install script should be moved from Application/Upgrade/ to Application/Install/.
