The previous recommend incantation would leave the process we read from
hanging around, even though it had finished. That gives you a
'defunct'/'zombie' process.

Show tags in commit view

### What does this MR do?
With this MR you can see the assigned tags for a commit in the commit view.
### Are there points in the code the reviewer needs to double check?
I don't think so. But it would be awesome if the reviewer can tell me how to add a tag to the sample_commit in spec/support/repo_helpers.rb.
Then I can add a test for the new tag_names_contains method as soon as possible :)

### Why was this MR needed?
At the moment if one click on a commit will see details such as: parent commit, amount of additions, deletions, but will not see if this commit has Tag linked to it.
Showing branch, tag details will give better overview about the commit

### What are the relevant issue numbers / Feature requests?
Feature request: http://feedback.gitlab.com/forums/176466-general/suggestions/3962044-show-tags-in-commit-view

print validation errors when gitlab-rake gitlab:import:repos fails for project

Currently, when gitlab-rake gitlab:import:repos is not able to import a project it justs prints "Failed trying to create project" to the console. There seems to be no way to find out what exactly has failed. Since the check uses validation, it should at least print the validation issues. That might be a bit cryptic, but may be better than leaving the user in the dark completely.
