[Tarantool-patches] [PATCH v1] gitlab-ci: set cleanup based on docker for all

[Alexander V. Tikhonov]

Set cleanup based on docker for all of the jobs to avoid of fails
when the job before change could use docker and reassigned the
temporary files in the working directory. If the docker is not
available than no need to use it for cleanup and cleanup runs
using shell. Gitlab-ci clean flags disabled and reorganized localy
as shown at [1].

Disabled gitlab-ci checkout default process as shown at [2] to be
able to fix repository before the checkout. Found that previously
run gitlab-ci jobs could change permissions files at repository
which broke the checkouts at the next jobs. Used for checkout
strategy [3], for submodule update strategy [4].

List of steps made localy instead of gitlab-ci preparations:

1. Check/clone the Tarantool repository with submodules.
2. For shell based jobs change ownership of all the sources
   to 'gitlab-runner' user. (NOTE: in Docker based jobs the
   'gitlab-runner' user is not known.)
3. Fetch Tarantool sources with branches and force checkout
   of the testing commit.
4. Update submodules recursively (use force where supports).
5. Cleanup all the sources from all files except from repository.
