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.

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

* 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

Fix typo in README.md

fix names of foreign arch packages
