    [MongoDB] Fix bug with reconnection to new master node

    Fixes bug with raising AutoReconnect exception when MongoDB ReplicaSet
    loses connection to primary node.

    Closes-Bug: #1309555

    Conflicts:
     ceilometer/event/storage/impl_db2.py
     ceilometer/event/storage/impl_mongodb.py
     ceilometer/storage/__init__.py
     ceilometer/storage/mongo/utils.py
            ceilometer/tests/storage/test_pymongo_base.py

    Conflicts are due to refactoring of the storage drivers and this patch
    has been modified to account for the refactor. The test case within the
    file test_pymongo_base.py was removed since equivalent test coverage
    was included in the cherry picked commit in the test_storage_scenarios.py
    file.
