[OE-core] [PATCHv2 3/3] oe-selftest: Add option to submit test result to a git repository.

[mariano.lopez at linux.intel.com]

From: Mariano Lopez <mariano.lopez at linux.intel.com>

This new option allows to commit the result to a git repository,
along with the results it will add a metadata file for information
of the current selftest run, such as: hostname, machine, distro,
distro version, host version, and layers.

This implementation will have a branch per different hostname,
testing branch, and machine.

To use this feature use:

oe-selftest <options> --repository <repository_link>
