WIP: adding the docker container for an openldap server

[scholtalbers]

XREF: https://github.com/scholtalbers/docker-galaxy-openldap/issues/1

I started this branch a while ago but couldn't actually get the ./buildlocal.sh working at the time, so this is the state I left it at (did do a rebase). What is needed is to actually get the auth_conf.xml in place, make sure the galaxy instance can connect and make a nicer/more comprehensive galaxy.ldif for the ldap server initialization.

I might work on this, but also happy if anyone takes over ;) - and happy for any (obvious) pointers on how to make this work.

@scholtalbers any plans here? :) I had recently a request for that feature :)
