Revert "Align to openstack python package index mirror"

This reverts commit 1c4a7944d003f9d627cece91fa2d2986de2c1d4d.

No other integrated projects are hard-coding the package index.  This
breaks anyone doing CI behind a firewall, and a workaround of -i on the
command line shouldn't be required to use tox with the project.

Changes that require dependencies in the mirror have to go through the
same process as everyone else to get them merged in the
global-requirements file and then served to the mirror so your change
can run with them.

Remove docutils pin

This was added to work around bug 1091333.  A new sphinx has been
released and so this is no longer necessary.

[Mongodb] Implement events on Mongodb and DB2

In this change events are written into database (Mongodb, DB2) and
retrieved from it.

Several methods were implemented for this purpose:
1. record_events --- store events into database
2. get_events, get_event_types, get_trait_types and get_traits --- get data
from db.
Add some attendant changes.
