Alembic isn't part of building Asterisk, so install_prereq doesn't have it included. It's also only necessary for database usage or creating migration scripts, so it has to be manually installed.

I don't believe we have anything specific except the normal usage for users of it[1]. This is because we don't do anything special with alembic or modify it. If you do the following:

cd contrib/ast-db-manage
alembic -c config.ini.sample revision -m "pjsip add norefersub"

It should work though.
