Delegate HA enable/disable to kvm-ha-service

  The kvm-ha-service now owns the HA lifecycle for hypervisors,
  including setting spec.maintenance=ha and the ConditionTypeHaEnabled
  and setting ConditionTypeHypervisorDisabled status condition after
  the compute service got disabled.

  Changes:
  - Delete HypervisorInstanceHaController and its tests
  - Remove enableInstanceHA, disableInstanceHA, updateInstanceHA,
    InstanceHaUrl from utils.go
  - Exclude MaintenanceHA from the maintenance controller's compute
    service disable logic, as the ha-service handles that case
