Fix trailing slash in teamcity_url

Originally opened at !2309 by @ctmay4.

As described in #3515, if you have trailing spaces in the the Teamcity server name, the service
will not work properly.  Switching from `URI.parse` to `URI.join` fixes it so that it works with
or without a trailing slash.

Fixes #3515.

API: Subscribe and unsubscribe from issues and merge requests

* Closes #6024 

This MR is based on !3611, which must be merged first.


See merge request !3615

The grafana-dashboards repository now contains _all_ GitLab.com
dashboards and thus requires some extra continuous queries to be set up.
The repository now also provided a way to automatically import/export
dashboards.

Fix high CPU usage when PostReceive receives refs/merge-requests/<id>

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/12661


See merge request !3651

Currently this works by loading the HAML partials via XHR. While this is
not the nicest setup it _is_ the easiest setup using the tools we
currently have.

Loading this data asynchronously doesn't make loading the related
MRs/branches itself faster, it merely ensures that loading the issue
itself is not slowed down.

Fixes gitlab-org/gitlab-ce#14949

API: Star and unstar a project

Add two new endpoints `POST /projects/:id/star` and `POST /projects/:id/unstar` to star and unstar a project.

Allow Omniauth providers to be marked as external

Related to #4009 

With this MR we will be able to allow the user to set which Omniauth Providers they would like to have as external. All users login in via these providers will be marked as external, even if they already had an account before. If the provider is removed form the list of external providers, the users will be marked as internal at their next login.

Add `Gitlab.com?` method

To be used as a feature flag for GitLab.com-only features, such as
welcome emails.

We will be careful to only use this to disable features or functionality
that do not make sense for any installations that aren't GitLab.com. We
will not use this to restrict features from other installations or keep
them "exclusive" to GitLab.com.
