Add OpenLDAP to manila-docker-container

This patch adds an OpenLDAP server and some LDAP utilities to the
manila-docker-container Docker image. It modifies the Dockerfile so it installs
the ``slapd`` and ``ldap-utils`` packages, calls the slapd.sh shell script,
which configures slapd, and makes the container start slapd automatically when
run.
