this commit enable relatives path for provisioning dashboards.
this enables easier dev setups

Closes #12061

* 9703-auth-proxy:
  go fmt fixes
  configure proxy environments for Transport property

related issue: https://github.com/grafana/grafana/issues/9703

* Add a full range option to sparklines

* line zero=false

Motivation:

* too many conditionals for config, better to be explicit
* different priorities: faster build for hot mode
* working SCSS sources for styles in hot mode

The biggest differences:

* removed linter from TS loader in hot (should be editor or precommit
 or responsibility)
* simplified styles loading
* hot needs more extensions to resolve
* removed commons chunking for hot
* removed devServer from dev

Reduced HMR time from 8s to 4s on my machine.

* upgrade all webpack loaders to recent version
* keep TS loader at 4.0.0 (5.0.0 requires webpack 4)
* remove unused json-loader

Resolves issue with postgres tests.
Also sets timezone of test instance and database to utc to resolve
mysql tests.
Closes #12065

* 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

* fix: another update to tz param generation

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