for free, trial and azure_lite highAvailability should be not set in created Runtime CR

[Disper]

Description
For free, trial and azure_lite highAvailability should be not set in created Runtime CR. Gardener will not allow to revert if this setting is set. For remaining plans it should use the configured value (currently: STAGE -> NODE), (PROD -> ZONE)

Expected result

• free, trials and azure_lite cluster should not have the .controlPlaneConfig.highAvailability set

Actual result
.controlPlaneConfig.highAvailability is set on all the plans

Steps to reproduce
Create a PROD->free/trial/azure_lite cluster

Fix: #1637

The fix is not working correctly. The e2e tests for aws, gcp and azure plans are all failing on KCP dev because KIM tries to apply an invalid failureTolerance value for the Gardener shoot:
