Fix alembic migration on MySQL 5.7
Presently, attempting to run alembic migrations for Octavia on a host using MySQL 5.7 as the database back-end fails with an error about a nullable field in a primary key. This commit fixes the offending migration and introduces a second, similar migration so that any existing installation using MySQL 5.6 or older also have this field set to be non-nullable.
