Refactor to allow shared contract between core and external backend plugins
allowing core backend data sources in Grafana to be implemented in same
way as an external backend plugin.
Use v0.67.0 of sdk.
Add tests for verifying plugin is restarted when process is killed.
Enable strict linting for backendplugin packages
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.

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

* 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
