Update GitLab Exporter to 7.0.6 to provide correct pipeline metrics
With gitlab-org/gitlab-exporter!118 (merged) a bug is fixed to make sure the correct queries are run for CE instances when reading the pipeline metrics from the database. This MR bumps the patch version to ensure this fix gets shipped with the next release.
Issue in the current gitlab-exporter: gitlab-org/gitlab-exporter#71 (closed)
EDIT: Also a EE bug was found, and is fixed in another patch version.
