git config missing on ROS2 farm

[mikaelarguedas]

We've been having jobs failing on build.ros2.org due to a lack of git config.

I have no idea how the puppet magic works but looking around it seems that the following snippet should cover setting up a git config:

buildfarm_deployment/modules/profile/manifests/jenkins/master.pp

Lines 12 to 21 in 30c7a91

	jenkins::cli::exec { 'configure_git_user':
	# semicolons are needed because the lines are joined with spaces rather than newlines.
	command => [
	'def gitscm_config = Jenkins.getInstance().getDescriptor("hudson.plugins.git.GitSCM");',
	'gitscm_config.setCreateAccountBasedOnEmail(false);',
	'gitscm_config.setGlobalConfigName("jenkins");',
	'gitscm_config.setGlobalConfigEmail("[email protected]");',
	'gitscm_config.save();',
	]
	}
