Description of problem:
Something in pulp is trying to do something with MongoDB with pymongo, and doing it in the wrong order.  Often, after restarting Satellite services ("katello-service restart") you'll see a few of these:

Feb  6 17:48:50 satellite1 pulp: py.warnings:WARNING: (31295-49792) /usr/lib/python2.7/site-packages/pulp/server/db/model/__init__.py:536: DeprecationWarning: update is deprecated. Use replace_one, update_one or update_many instead.

Feb  6 17:48:50 satellite1 pulp: py.warnings:WARNING: (31295-49792)

I'm told the deprecations are being handled in another BZ, but the UserWarning for pymongo I haven't seen anything about.


Version-Release number of selected component (if applicable):
Satellite 6.2.7 and RHEL7 updated as of 2017-02-06.

How reproducible:
Basically every time you restart Satellite services,

Steps to Reproduce:
1. Restart with "katello-service restart"
2. Wait a bit.
3. Watch /var/log/messages

Actual results:
It's only a warning, but I wouldn't have thought it was something that couldn't be fixed.

Expected results:
No warning, MongoClient.  Perhaps create MongoClient with connect=False, or create client after forking.

Additional info:
None
