Field to define custom commit message

[dariooddenino]

Hi! Today I got another idea that would be nice to have. I have an org repo syncd to github for which I really don't have meaningful commit messages to use. It would be great to be able to define a custom commit message per repository. Would be even better with some simple tokens :)

E.g:

locations:

• type: git location: ~/EF force: true commit_message: Daily update {datetime}
