Public bug reported:
Installed Octavia via charm-octavia using bionic-stein.
When the charm tried to execute a database migration
sudo octavia-db-manage upgrade head
it failed with the following error:
2019-04-29 11:49:20.096 22569 ERROR octavia-db-manage
sqlalchemy.exc.InternalError: (pymysql.err.InternalError) (1105,

It looks like the spares_pool table doesn't have a primary key.

Fix spare amphora check and creation
This patch fixes an issue when the SparesPool table is empty that blocks
spare amphorae creation. It creates a new spares pool entry if the table
is empty.
