Backend plugins: Renderer v2 plugin (#23625)
grafana-plugin-model is legacy and is replaced by new backend 
plugins SDK and architecture. Renderer is not part of SDK and 
we want to keep it that way for now since it's highly unlikely there 
will be more than one kind of renderer plugin.
So this PR adds support for renderer plugin v2.
Also adds support sending a Device Scale Factor parameter to the 
plugin v2 remote rendering service and by that replaces #22474.
Adds support sending a Headers parameter to the plugin v2 and
remote rendering service which for now only include 
Accect-Language header (the user locale in browser when using 
Grafana), ref grafana/grafana-image-renderer#45.
Fixes health check json details response.
Adds image renderer plugin configuration settings in defaults.ini 
and sample.ini.

Rendering: Store render key in remote cache (#22031)
By storing render key in remote cache it will enable
image renderer to use public facing url or load
balancer url to render images and thereby remove
the requirement of image renderer having to use the
url of the originating Grafana instance when running
HA setup (multiple Grafana instances).

Fixes #17704

Alerting: Fix image rendering and uploading timeout preventing to send alert notifications (#21536)
* svc alerting - use a shorter ctx to upload the img
This will prevent timeout on img upload to cancel the notifications from being sent

* components img uploader - pass the ctx to aws lib

* make webdavuploader use the ctx

* make azureblobuploader use the ctx

* rename uploadImage() to renderAndUploadImage()
for better clarity about what this method work

* Use timeout + 2s for plugin renderer (same as service and phantomjs)

* Make sure that original EvalContext is updated after render and upload

* Verify notification sent even if render or image upload times out

* fix lint

* fixes after review

5c0fbbf7c8 improve remote image rendering (#13102)
* 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.

Backend image rendering as plugin (#11966)
* rendering: headless chrome progress

* renderer: minor change

* grpc: version hell

* updated grpc libs

* wip: minor progess

* rendering: new image rendering plugin is starting to work

* feat: now phantomjs works as well and updated alerting to use new rendering service

* refactor: renamed renderer package and service to rendering to make renderer name less confusing (rendering is internal service that handles the renderer plugin now)

* rendering: now render key is passed and render auth is working in plugin mode

* removed unneeded lines from gitignore

* rendering: now plugin mode supports waiting for all panels to complete rendering

* fix: LastSeenAt fix for render calls, was not set which causes a lot of updates to Last Seen at during rendering, this should fix sqlite db locked issues in seen in previous releases

* change: changed render tz url parameter to use proper timezone name as chrome does not handle UTC offset TZ values

* fix: another update to tz param generation

* renderer: added http mode to renderer service, new ini setting [rendering] server_url
