Unversioned image on placement chart

[Thiago Paiva Brito]

Brief Description
-----------------
On commit 03d78718966e85eb0094ed48062d9d33f3519f85 of openstack-helm a new image was introduced to execute the db migrations as a "latest" form. During the upversion of openstack-helm on openstack-armada-app, we started carrying this patch but that might affect our stability of the release in the future in case a new incompatible image is released

    Pin placement's db_migrate image version

    On commit 03d78718966e85eb0094ed48062d9d33f3519f85 of
    openstack-helm a new image was introduced to execute the db
    migrations as a "latest" form. This commit pins the version of
    that image for stx-openstack to a fixed version to avoid that
    future image builds of porthole-mysqlclient-utility breaks the
    app.
