Check permissions when sharing project with group

## Summary

Unprivileged user was able to share project with group he didn't have access to, and therefore gain partial access to that group, which opened possibilities for further actions like listing private projects in that group.

See https://gitlab.com/gitlab-org/gitlab-ce/issues/15330

## Fix

This change introduces additional check for group read access.

## Further work

We can think about preventing such problems in the future (this is quite common problem) by moving permissions checks to another layer of abstraction (TBD).

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/15330

Make before_script and after_script overridable

This is makes it possible to overwrite the before_script and after_script at job level.

This is continuation of https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/3771


See merge request !3772

Implement after_script which allows to do cleanups as part of the build process

This implements `after_script` in global context.

The `after_script` will be executed always after the job, even if the job were canceled.

This requires changes on Runner side that will be implemented in 1.2.

Closes #15330

Fix prepare build execution in docker environment

In newest versions of docker the `/.dockerinit` file doesn't exists any more (https://github.com/docker/docker/pull/19490). And oo our builds are failing, because the `./scripts/prepare_build.sh` script isn't installing required dependencies.

This MR fixes the problem with backward compatibility for oldest docker environments.

Added System Hooks for push and tag_push

Implements `push` and `tag_push` events for System Hooks.

They are based on Webhooks Events but without any deprecated item. We don't send commits too.
We are implementing this, to be used by Geo repository syncing (gitlab-org/gitlab-ee#76).

These hook events will be sent only when the respective configuration flags are set to true.
UI changes to admin screen will be made in another MR.
