Description of problem:

When i am trying to configure dataprotectionapplication.spec.configuration.nodeAgent.loadConcurrency.PrepareQueueLength, it does not recognise it, as there is no such field in DPA.

Version-Release number of selected component (if applicable):

OADP 1.5.3

How reproducible:

always

Steps to Reproduce:
Setup DPA with dataprotectionapplication.spec.configuration.nodeAgent.loadConcurrency.PrepareQueueLength set to 2, lets say

Actual results:

DPA removes it

Expected results:

DPA should recognise it, it needs to be added as it is a velero 1.17 feature.
