Subject: Add schema-compat-relevant-subtree

Add a schema-compat-relevant-subtree configuration option, listing the
only parts of the DIT that we should ever look at, either as source
entries or as other entries which contain data which might be pulled in
as part of computing the contents of compat entries.

This is more or less the whitelist to schema-compat-ignore-subtree's
blacklist.
