STARTTLS, custom/valid certificate support, runtime configuration & other enhancements

AnalogJ commented 3 years ago

I added the following to your (incredibly useful) image:

support for STARTTLS (forced and unforced).
instructions for how to generate valid certificates for using Letsencrypt
configuration that can be set/overridden via environmental variables
- ENV LDAP_DOMAIN=planetexpress.com
- ENV LDAP_ORGANISATION="Planet Express, Inc."
- ENV LDAP_BINDDN="cn=admin,dc=planetexpress,dc=com"
- ENV LDAP_FORCE_STARTTLS="false"
Example commands for Ldapsearch.
Reorganized the container to use s6-overlay, so its easier to customize/configure the container at runtime (rather than having to rebuild the image everytime a change is necessary).

Hopefully you find it useful enough to merge, but either way, thanks for all your hard work @rroemhild
