TODO: dsdb/repl: Reduce noice during replication of Windows 2012 R2 schema by ignoring more attributes

We do not need to know about the attributes that are permitted in a
class, nor the permitted parent or subClass values to convert the
objects from DRS, as we never enforce schema restrictions on DRS
replicated objects.

This will not change how we eventually succeed or fail, because we
have to convert the object in the end, but this means less looping
while we do that.
