* improve remote image rendering
- determine "domain" during Init() so we are not re-parsing settings
on every request
- if using http-mode via a rednererUrl, then use the AppUrl for the
page that the renderer loads. When in http-mode the renderer is likely
running on another server so trying to use the localhost or even the
specific IP:PORT grafana is listening on wont work.
- apply the request timeout via a context rather then directly on the http client.
- use a global http client so we can take advantage of connection re-use
- log and handle errors better.
* ensure imagesDir exists
* allow users to define callback_url for remote rendering
- allow users to define the url that a remote rendering service
should use for connecting back to the grafana instance.
By default the "root_url" is used.

* rendering: fixed issue with renderKey where userId and orgId was in mixed up, added test for RenderCallbackUrl reading logic
* wip: start on refactoring settings
* settings: progress on settings refactor
* refactor: progress on settings refactoring
* fix: fixed failing test
* settings: moved smtp settings from global to instance
