Description of problem:
CDIConfig was recently moved to the CDI CR, but in d/s we cant change fields in the CDI CR due to HCO reconciliation

Version-Release number of selected component (if applicable):
2.6.0

How reproducible:
100%

Steps to Reproduce:
1. Edit CDI Config in CDI CR (spec.config)

Actual results:
Changes reverted

Expected results:
Changes saved

Additional info:
- CDIConfig was recently moved to the CDI CR
- It was recently decided that HCO will not expose new APIs regarding strict reconciliation until 2.7
