[Tarantool-patches] [PATCH v1] gitlab-ci: fix deployment of tagged commits

[Alexander V. Tikhonov]

Found that tagged commits were not run the deployment gitlab-ci jobs.
To fix it added 'tags' label for deployment and perfomance jobs. Also
found that after the commit tagged it has tag label in format 'x^0'
and all previous commits till the previous tag became to have tags in
format 'x~<commits before>' like 'x~1' or 'x~2' and etc. So the check

  if git name-rev --name-only --tags --no-undefined HEAD ; then

became always pass and previous commits on rerun could began to deploy.
To fix it was used gitlab-ci environment variable 'CI_COMMIT_TAG', it
shows in real if the current commit has tag and has to be deployed.
