InfluxDB: backend migration (run query in explore) (#43352)

* InfluxDB backend migration

* Multiple queries and more

* Added types

* Updated preferredVisualisationType

* Updated model parser test to include limit,slimit,orderByTime

* Added test for building query with limit, slimit

* Added test for building query with limit, slimit, orderByTime and puts them in the correct order

* Add test: Influxdb response parser should parse two responses with different refIDs

* Moved methods to responds parser

* Add test to ensure ExecutedQueryString is populated

* Move functions out of response parser class

* Test for getSelectedParams

* Merge cases

* Change to const

* Test get table columns correctly

* Removed unecessary fields

* Test get table rows correctly

* Removed getSeries function

* Added test for preferredVisualisationType

* Added test for executedQueryString

* Modified response parser

* Removed test

* Improvements

* Tests

* Review changes

* Feature flag rename and code gen
