Gitty Housekeeping Endpoint

As a developer, I have an endpoint on Gitty that triggers housekeeping mechanism on a project.
Cmd to execute is git gc --prune=now; git repack -f -a -d --depth=100 --window=100
Ideally, depth and window are configured from properties file.

AC:

• I have an endpoint on Gitty to execute a HK cmd
• I can configure depth and window from Gitty configuration file.
• The result of the execution of the HK is stored in Audit
