installing proliantutils without constraints breaks ironic

[Pavlo Shchelokovskyy]

Yesterday, 2017-03-23, a new version of pysnmp (4.3.5) was released. Apparently it became incompatible with pyasn1 version enforced by openstack's global requirements and constraints (0.1.9) which manifests itself in the following manner:

when proliantutils is installed without forcing constraints, no driver defined in ironic package can be loaded by its entrypoint (even fake) with the following error:

We need to start enforcing global constraints from openstack/requirements everywhere.

Making a note that pysnmp 4.3.9 and pyasn1 0.3.1 are out (presumably fixing the above regression) also reflected in the updated openstack/requirements constraints.
