Fix application_settings JOIN condition for CiBuildsProbe

Closes #71

See merge request gitlab-org/gitlab-exporter!119

After https://gitlab.com/gitlab-org/gitlab/-/merge_requests/29981, we cannot assume an application_settings
with ID=1 exists. But we know that there will only be one record in that table, so we can change the JOIN
condition to TRUE safely.

Add Secure scanning tools

Remove usage of ghost column

See merge request gitlab-org/gitlab-exporter!116

Ghost column was migrated to user_type column and will be removed soon. So we need to update exporter to rely on user_type only before we actually remove ghost column from DB.

Bump version to 7.0.3

Speed up mirror row count queries

See merge request gitlab-org/gitlab-exporter!113

We can discard records from before 2020-03-28 as they are almost
certainly on free plans.

Improve mirror queries

See merge request gitlab-org/gitlab-exporter!111

We appear to have some data integrity issues on GitLab.com where some
projects are marked as public but their namespace isn't. This project
won't actually be public and so won't get Gold features for free, so we
exclude them from the query.

Fix plan checks for mirror queries

See merge request gitlab-org/gitlab-exporter!110

Plans are no longer through namespace.plan_id, but through the root
namespace via gitlab_subscriptions.

Add Global stats

fix: expose runner_type directly

Closes #48

See merge request gitlab-org/gitlab-exporter!108

Before we exposed 'is_shared', but this value doesn't exist anymore since gitlab-foss@ca93faf1 so it only works previously added shared runners
I've decided to directly expose the runner_type variable, since it allows for more detailed metrics, instead of just using is_shared

Closes #48

Update pg gem to v1.2.2

See merge request gitlab-org/gitlab-exporter!107

This adds support for Ruby 2.7 and PostgreSQL 12. Omnibus is also
shipping two versions of the pg gem (v1.2.2 and v1.1.4), so let's make
this consistent.

Update unicode-display_width (Rubocop dependency)

See merge request gitlab-org/gitlab-exporter!105

It was previously at v1.1.0, which uses the deprecated `Gem.gunzip` method.
The usage of deprecated functions was removed in unicode-display_width v1.3.3.
