Explore now uses the timezone of the user to decide if local browser
time or UTC should be used.
- Now uses TimeRange instead of RawTimeRange in explore item
state tree and only parsing actual time in a few action
handlers.
- Time picker should now properly handle moving back/forward and
apply time range when both utc and non utc time zone.
- URL range representation is changed from YYYY-MM-DD HH:mm:ss
to epoch ms.
- Now uses AbsoluteTimeRange in graph component instead of moment.
- Makes a copy of the time range passed to timeSrv to make sure immutability
of explore time range when for example elasticsearch test datasources uses
timeSrv and sets a time range of last 1 min.
- Various refactorings and cleanup.
Closes#12812
- moved ActionTypes to `./state/actionTypes`
