[JENKINS-32143] Set git merge timeout

When using Merge Before Build, sometimes throws error:

git merge --ff df24f37fedf6048881cc0683a782c975b0bd8db7 # timeout=10

ERROR: Timeout after 10 minutes

> git config core.sparsecheckout # timeout=10

> git checkout -f df24f37fedf6048881cc0683a782c975b0bd8db7 # timeout=20

FATAL: Could not lock repository. Please try again

and next build in the same workspace is failed with error:

FATAL: Could not lock repository. Please try again

This happens because my repositore is very big. I want set a merge timeout or kill git process before next try.

Thanks
