Update gitlab-git-http-server to 0.2.9
Version 0.2.9 adds the option to run the built-in Golang profiler. We will have to create a new attribute in the internal cookbook, and render it in the sv-gitlab-git-http-server-run template.
default['gitlab']['gitlab-git-http-server']['pprof_listen_addr'] = "''" # put an empty string on the command line
