Decouple munge ansible tasks from slurm_client role during deploy

Closes #299

See merge request !228

Closes https://gitlab.rc.uab.edu/rc/hpc-factory/-/issues/299

Munge is not a service expected to be on a slurm client like a compute
node VM. An instance that is not a slurm client like OOD doesn't need
slurmd. Move the munge tasks so that they can be turned on independently

BUGFIX: Make build and cleanup ENV match

See merge request !227

Avoid the deploy when build fails for OOD

Closes #282

See merge request !226

If the build job fails we don't want to run the deploy job. We use needs
keyword to accomplish it. We use optional: true so that if the needed
job is not present, the job can start when all other needs requirements
are met.

Script to list sched pipelines with ID and description

Closes #287

See merge request rc/hpc-factory!224

The python-gitlab cli allows listing only sched pipeline IDs of a
project. This script allows us to list the description slong with it.
This helps a user to look at pipeline list and decide which sched
pipeline they would read/write the variables.

Fix f-string error due to double quotes when dereferencing a list element

Closes #284

See merge request rc/hpc-factory!220

Double quotes conflicted with the f-string syntax. Using single
quotes avoids syntax errors when accessing dict keys.

fix: Use the image name format formed from image_tag

See merge request rc/hpc-factory!217

remove explicit check for pipeline source, since CI_MERGE_REQUEST_IID
will always be set in MR pipelines, skipped otherwise.

Move build var overrides to PKR_VARS_extra_vars

Closes #266

See merge request rc/hpc-factory!215

Prevents running prod from getting deleted because it will be the
oldest instance in the sorted list of servers to delete.
Also allows rollback if the new prod instance fails after cutover.

Replaces image-based sort with filtering by tags and sorting by
creation time to determine old instances for deletion.
This also simplifies the previous logic to print a list of servers
for deletion

The NUM_SERVERS_TO_KEEP value should always be postive so that the
list of servers to delete will be calculated correctly.

By default keep the previously deployed instance.
Any instance older than that will be deleted based on the
NUM_SERVERS_TO_KEEP variable.
