Revert "Enable keystone token caching by OSC"

This reverts commit 67630d4c52.

Reason for revert: Seeing random failures across jobs as sometimes
'keyring_pass.cfg' gets duplicated keys and that makes executions
of any openstackclient command to fail until the file is removed.
This should be handled before re enabling the token caching again.
