Adds tab indexing to the control for allocation and changes label names.
Corrects mistake that led to exception being thrown when the Disk Size is decreased in the the New Disk Dialog.
Created ThinProvisioningParametersControl user control using existing code to have the thin provisioning settings at one place. It needs to be initialized by providing an SR and it will expose its internal state via NewSMConfig property that we need at other places.
This does not include refactoring of existing code or replacing existing code to use this new control, but the new Conversion dialog is using this. Next step would be to remove existing code and start using this new ThinProvisioningParametersControl instead.
