Fix up VERSION for each of the applications
* There is no 0.0.1 helm version for jupyterhub. Use the latest version instead
* `:nginx` is not a valid chart version. Lock the ingress application GitLab installs to the latest chart version.
* Use the latest gitlab-runner chart to prevent GitLab installing older versions when users have been installing the lastest version

Always install from the VERSION and not the database `version` column.
This should fix cases like https://gitlab.com/gitlab-org/gitlab-ee/issues/6795 in
the instances where an install command failed previously, which locked the version
in the database to an older version.

Also, ensure that the version column is updated to the version we are
installing.

Add specs to show how previously failed appplications will be handled when the helm installation is run again

Our friends at GitHub show the programming languages for a long time,
and inspired by that this commit means to create about the same
functionality.

Language detection is done through Linguist, as before, where the
difference is that we cache the result in the database. Also, Gitaly can
incrementaly scan a repository. This is done through a shell out, which
creates overhead of about 3s each run. For now this won't be improved.

Scans are triggered by pushed to the default branch, usually `master`.
However, one exception to this rule the charts page. If we're requesting
this expensive data anyway, we just cache it in the database.

Edge cases where there is no repository, or its empty are caught in the
Repository model. This makes use of Redis caching, which is probably
already loaded.

The added model is called RepositoryLanguage, which will make it harder
if/when GitLab supports multiple repositories per project. However, for
now I think this shouldn't be a concern. Also, Language could be
confused with the i18n languages and felt like the current name was
suiteable too.

Design of the Project#Show page is done with help from @dimitrieh. This
change is not visible to the end user unless detections are done.

Added gitlab-pages update instructions.
