Allow undercloud installations/upgrades from custom t-h-t, similarly to
overcloud_templates_* et al.
Unify and share custom t-h-t install script for OC and UC and mixed
update/upgrade cases via new shared role tht-prep-config.
To diverge undercloud from overcloud install/update/upgrade cases, use
the following shared mappings (vars on the right correspond to UC
cases):
* tht_templates_path: undercloud_templates_path (defaults to RPM dir)
* tht_templates_repo: undercloud_templates_repo
* tht_templates_branch: undercloud_templates_branch
* tht_templates_refspec: undercloud_templates_refspec
and a 2nd group (defaults set to do nothing, but only disable the
t-h-t prepare script's code blocks under control of those):
* composable_scenario: undercloud_composable_scenario
* upgrade_composable_scenario: undercloud_upgrade_composable_scenario
* prep_post_hook_script: undercloud_prep_post_hook_script
* download_templates_rpm: download_undercloud_templates_rpm
* tht_rpm_url: undercloud_tht_rpm_url
Those in group 2 may be customized to mimic the overcloud mixed
upgrades logic for underclouds/all-in-one for future use.
And for overclouds respectively, use mappings:
* composable_scenario: remains unchanged
* upgrade_composable_scenario: remains unchanged
* prep_post_hook_script: overcloud_prep_post_hook_script
* download_templates_rpm: download_overcloud_templates_rpm
* tht_rpm_url: remains unchanged
* tht_templates_path: overcloud_templates_path
