* removes readonly editor role

* adds viewersCanEdit setting

This enable you to allow viewers to edit/inspect
dashboards in grafana in their own browser without
allowing them to save dashboards

* remove read only editor option from all dropdowns

* migrates all read only viewers to viewers

* docs: replace readOnlyEditor with viewersCanEdit

* Thib17-master:
  removes verbose logging
  Add a per-notifier ShouldNotify()

This way we are able to edit notification behavior per notifier.
This would be usefull to let some notifiers send notifications,
even when the state doesn't change, or with custom condition.

Wait for all sub routines to finish before closing Grafana

The datasource uses the default region in the query if the region
is "" in the settings. However setting the region to an empty string
is almost impossible and rendered incorrectly.

This commit introduces a special value "default" for region which
is shown in the drop down and is translated to the default region
of the data source when performing queries.

simple solution for waiting for all go sub routines to
finish before closing Grafana. We would use errGroup
here as well but I dont like spreading context's all
over the place.
