* Add plugin using pam authentication
Adds an additional plugin which us authenticating against
the PAM unix backend and exposing users and groups local
to the machine glauth is running on.

In case of the PAM backend this will be used to authenticate against
the local PAM database.

Modernizes the implementation of Search() to make use of the helper
functions provided by LDAPOpsHelper.

Fix#141.
With this change, a github action is added that builds a multiarch docker image on every commit, supporting x86_64, aarch64 and arm/v7.
When the action is triggered on a release or tag, it also uploads the versioned image to github container image registry.
