Feature 11007: replace charmed mongodb with bitnami helm chart

This change replaces charmed MongoDB with Bitnami helm chart. The
values passed to the helm chart use the same service name that existed
previously, mongodb-k8s, so that no other changes are required in the
rest of modules.

It also modifies OSM health checks to successfully pass mongodb health
check.
