Remove usage of sudo

Remove usage of sudo and update prompts.

Fix instructions for creation of stack user:
* These substeps need to be run as root like its said in the intro.

Remove folder .tx from git tree

Tracking .tx by git will cause an error while running the script:
propose_translation_update_manuals.sh
Folder .tx could be created on the fly.
So this patch removed folder .tx from git tree.

Same as openstack-manuals
