[OE-core] [PATCH 12/19] oe-build-perf-test: tag results committed to Git

[Markus Lehtonen]

Create a Git tag when committing results to a Git repository. This patch
also implements --commit-results-tag command line option for controlling
the tag name. The value
is a format string where the following fields may be used:
- {git_branch} - target branch being tested
- {git_commit} - target commit being tested
- {tester_host} - hostname of the tester machine

Tagging can be disabled by giving an empty string to
--commit-results-tag. The option has no effect if --commit-results is
not defined.
