Bug#979473: ITP: golang-gitlab-gitlab-org-labkit -- A minimalist library to provide functionality for Go services at GitLab

[Vipul Kumar]

control: retitle -1 ITP: gitlab-labkit

Hi! all,
I'm renaming 'golang-gitlab-gitlab-org-labkit' package to 
'gitlab-labkit', to make things consistent with other Go based Gitlab's 
packages [1].

Cheers,
Vipul
