Remove `gitlab.fullpath` from git config in repositories
For #4524 (closed)
This Git config was set to denote the project's full path of a repository on Gitaly side. We scheduled the removal this feature in this epic: &8953 (closed).
After the corresponding RPCs are removed, we need to clean up the
unused gitlab.fullpath
git config in each repository. To do so, this
commit implements a stale data cleaning task. This task is triggered
as a part of the periodic housekeeping scheduler or by the
OptimizeRepository RPC.
