Duplicate POST request to create a token

[lucky]

In Queens release, When "openstack resource provider show <uuid>" command is executed, it is found that duplicate entries are logged in file "keystone_wsgi_main_access.log" for creating token.

keystone_wsgi_main_access.log
1. 172.30.66.178 - - [02/May/2018:12:37:47 +0530] "GET /v3 HTTP/1.1" 200 197 "-" "osc-lib/1.9.0 keystoneauth1/3.4.0 python-requests/2.14.2 CPython/2.7.5"

2. 172.30.66.178 - - [02/May/2018:12:37:47 +0530] "POST /v3/auth/tokens HTTP/1.1" 201 7792 "-" "osc-lib/1.9.0 keystoneauth1/3.4.0 python-requests/2.14.2 CPython/2.7.5"

3. 172.30.66.178 - - [02/May/2018:12:37:47 +0530] "POST /v3/auth/tokens HTTP/1.1" 201 7792 "-" "osc-lib/1.9.0 keystoneauth1/3.4.0 python-requests/2.14.2 CPython/2.7.5"

From above logs entries, it has been found that log 2 and 3 are identical.
Ideally there should be only one post request to generate a token.

It's a openstackclient's behavior. A similar bug is here: https://bugs.launchpad.net/python-openstackclient/+bug/1648428

Not related to Keystone itself.
