Port-chain delete port-pair details also

[vks1]

Currently port-chain delete leads to delete of port-pair details also from db. If tried to recreate port-chain with same ppg and classifier, create fails.

Steps to reproduce:

1. Create port-chain (pc1) with classifier class1 and port-pair-group ppg1.
2. Delete pc1
3. Redo (1).

Hi Vikash, I can't reproduce this issue, can you more details about the port chain being created?
Non-portpair portpairdetails should be removed from the db when the chain is deleted.

Hi Igor,

I created a port chain (pc1) and then deleted the same pc1 (only). I tried to recreate the same pc1 with the same port-pair group and flow classifier and it failed. I checked the log. Please find it here:

And after I debugged:
https://github.com/openstack/networking-sfc/blob/master/networking_sfc/services/sfc/drivers/ovs/driver.py#L344

pd1 was None as the DB entry was getting deleted.

Hi Vikash,

I still can't reproduce the issue, see http://paste.openstack.org/show/603388. Tested with latest master (17c537b35d41a3e1fd80da790ae668e52cea6b88), I expect there is something else triggering this issue for you, can you provide more context please? Also, can you test this commit without any other changes?
