Fix performance regression adding rules to security groups 
Sometime between liberty and pike, adding rules to SG's got
slow, and slower with every rule. Streamline the rule create path,
and get close to the old performance back.

Two performance fixes:
1. Get rid of an n^2 duplicate check, using a hash table instead,
on bulk creates. This is more memory intensive than the previous loop,
but usable far past where the other becomes too slow to be useful.
2. Use an object existence check in a few places where we do not
want to load all of the child rules.

Also squashed in:
Restore tenant_id check on security group rule adds to previous semantic

We switched from swapping the tenant_id in the context to explicitly
checking the db column. Switch back, and a test that checks for
not breaking this rather odd behavior. At least, until we decide
to fix it as a bug.
