Certificate verification warnings when TLS is enabled

[Alexander Rubtsov]

=== Environment ===
* Mirantis OpenStack 9.2
* TLS termination is enabled
* HTTPs endpoint is specified

=== Description ===
There are the following certificate verification messages appears while using CLI commands:
/usr/lib/python2.7/dist-packages/urllib3/util/ssl_.py:315: SNIMissingWarning: An HTTPS request has been made, but the SNI (Subject Name Indication) extension to TLS is not available on this platform. This may cause the server to present an incorrect TLS certificate, which can cause validation failures. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#snimissingwarning.
  SNIMissingWarning
/usr/lib/python2.7/dist-packages/urllib3/util/ssl_.py:120: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.
  InsecurePlatformWarning

Please install/update the modules required to get rid of the insecure requests so that the verification will pass

=== Steps to reproduce ===
1) Install 9.x master node
2) Deploy a new environment with TLS enabled:
Settings --> Security--> TLS for OpenStack public endpoints
3) Source the Keystone HTTPs endpoint for CLI:
export OS_AUTH_URL='https://public.fuel.local:5000/v2.0'
4) Run some OpenStack component CLI command:
nova list

=== Actual result ===
# nova list
/usr/lib/python2.7/dist-packages/urllib3/util/ssl_.py:315: SNIMissingWarning: An HTTPS request has been made, but the SNI (Subject Name Indication) extension to TLS is not available on this platform.

sla2 for 9.0-updates

[Stanislaw Bogatkin (sbogatkin)]

It does not affect anything, actually, but needed many efforts to migrate onto new libraries. Moved to low.

[Denis Meltsaykin (dmeltsaykin)]

Won't Fix for 9.2: the bugs of low importance/impact are not accepted for the maintenance updates.
