APS: Deletion Support for Pre-provisioned Configurations

Problem in EFA 2.3.2

Creation of EFA entities (PO and EPG) on an admin down device followed by the Deletion of the same EFA entities (PO and EPG) on the same admin down device used to fail even though the configuration was never pushed to the devices.

Solution in EFA 2.4.0 and above

Succeed the deletion of the EFA entities (PO and EPG) if the resultant configuration to be deleted has never been pushed to the devices.

Pre-provisioned config

The pre-provisioned config is present in EFA DB and not present on the SLX.
