deprecation warning for collection_names() method

[fuxjezz]

Hi,

if "last_primary_server" in db.collection_names(): 

on line 1389 throws a deprecation warning:

root@mdnode1:/home# ./check_cluster.py -A replica_primary -r rsmain -W 15 -C 30
./check_cluster.py:1389: DeprecationWarning: collection_names is deprecated. Use list_collection_names instead.
  if "last_primary_server" in db.collection_names():
OK - Primary server has not changed

changing it into :

 if "last_primary_server" in db.list_collection_names():

seems to silence the warning.

Kind regards,

Ruben
