person event subscriber handling pre and post event allowing persons to be filtered by local data attributes configured in bundle config

We had one use case where the LDAP server didn't support encryption,
so support that too.

(and fix some deprecation warnings uncovered by this)

So the user can decide between SSL/TLS.
We still default to encryption on and use the default ports since
no one required something different until now and
to not bloat the config.
