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.

Enables adding a section `plugin.<plugin id>` and key/value to
Grafana configuration file which will be converted and sent
as environment variables to the backend plugin.
Also sends some additional environment variables, Grafana
version (GF_VERSION), Grafana edition (GF_EDITION) and
enterprise license path (GF_ENTERPRISE_LICENSE_PATH).

Use v0.19.0 of SDK.
Support handling of streaming resource response.
Disable gzip/compression middleware for resources
to allow chunked/streaming response to clients the gzip
middleware had to be disabled since it buffers the full
response before sending it to the client.

Backend plugins is recommended to use hclog with json
formatting to get proper log output in grafana server log.
Old hclog-wrapper.go that I deleted while back is still in
the repo so deletes that.
