Add group and instance level integration tests

This adds an initial test of the Mattermost Slash Command integration
for group- and instance-level.

This is an initial effort in order to have coverage for
https://gitlab.com/gitlab-org/gitlab/-/issues/331262.

Further tests will be added in
https://gitlab.com/gitlab-org/gitlab/-/issues/331325.
