Changed how react panels store their options (#15468)

Changed how react panels store their options

* Added a ReactPanelPlugin as the interface that react panels export, this way react panels have clearer api, and gives us hooks to handle migrations and a way for panel to handle panel changes in the future
* Moved gauge value options into a sub oject and made editor more generic, will be moved out of gauge pane later and shared between singlestat, gauge, bargauge, honecomb
* Also remove nested options prop that was there due to bug
* Added missing Gauge props
* Fixed gauge issue that will require migration later and also value options editor did not handle null decimals or 0 decimals
* Fixed unit tests
* More fixes for react panels
