Not able to bring up the cluster using contrail-command in master branch

[musharani]

The below error is seen while trying to bring up the cluster using contrail-command in master branch.

Build - master-395.

Setup also available.
nodec59 - contrail-command
nodek12 - cluster

[root@nodec59 ~]# docker exec contrail_command tail -f /var/log/ansible.log
  File "/usr/lib/python2.7/site-packages/ansible/template/__init__.py", line 279, in _get_filters
    plugins = [x for x in self._filter_loader.all()]
  File "/usr/lib/python2.7/site-packages/ansible/plugins/loader.py", line 426, in all
    self._module_cache[path] = self._load_module_source(name, path)
  File "/usr/lib/python2.7/site-packages/ansible/plugins/loader.py", line 339, in _load_module_source
    module = imp.load_source(full_name, path, module_file)
  File "/usr/share/contrail/contrail-ansible-deployer/playbooks/roles/contrail_deployer/filter_plugins/calculate_contrail_roles.py", line 9, in <module>
    import requests
ImportError: No module named requests

Tried the work around which is mentioned in the bug https://bugs.launchpad.net/juniperopenstack/+bug/1803809.
But that is not working if we use contrail-command for provisioning.
