Allow to save and apply inherited templates on service desk issues
Backend part of #299084 (closed)
What does this MR do?
Allows applying inherited issue templates on service desk issues.
Allows saving file_template_project
id on ServiceDeskSetting
model to look for issue templates on specific projects.
A frontend follow-up MR is needed to replace the current template selector on project settings with one that also supports persisting inherited issue templates on backend. I created a snippet of how it can be done $2174097. It can be used by frontend team as a starting point, I also wrote a couple of feature specs to ensure it works with the current code.
Database work to support this change has been introduced on !67546 (merged).
