More granular "@osrf-jenkins run tests"

Commenting "@osrf-jenkins run tests" on a pull request will retrigger all available Jenkins jobs for that branch. But often, we only really need to trigger one of them, but end up triggering all for convenience.

It would be nice to support something like "@osrf-jenkins run linux tests"

the GitHub pull request builder plugin provides the full test of any comments that trigger a build in the ghprbCommentBody parameter; see the following for example:

• https://build.osrfoundation.org/job/generic-release-homebrew_triggered_bottle_builder/14/parameters/

So it should be straightforward to parse commands from the comment text. I'm not sure how to change which jobs are triggered, since that logic is defined at job creation in the following file:

• https://github.com/ignition-tooling/release-tools/blob/master/jenkins-scripts/dsl/_configs_/OSRFCIWorkFlowMultiAnyGitHub.groovy

Maybe we need to set up each job separately instead of using OSRFCIWorkFlowMultiAnyGitHub? Then we could add custom trigger phrases for each job.

I learned this week that if I click Retry instead of Rebuild on a Jenkins build, the GitHub checks get updated automatically. So for now this is a good temporary solution for me.
