Store migrations in a migrations db (#1992)

Browse Source 
* Store migrations in a migrations db

Added the -p flag to run_migrations for pipeline to run from
environment variables

Created meta-migrations script to pre-populate migrations_vault_dev
tables with run migrations for those already using the last_migrations
file

* Update dev/helpers/mssql/migrate_migrations.sh
