relaxing "CP list size must be >= OpVol list size"

[issmith1]

For TCL4 event, NASA is dropping the requirement for providing a full list of Contingency Plans. USS implementations should remove this validation from the PUT Operation endpoint.

NASA learned recently that Tcl4valtests is not enforcing this requirement.

Inclusion of this requirement is under consideration for the wrapup of the USS Spec

https://raw.githubusercontent.com/nasa/utm-apis/v4-draft/utm-domains/utm-domain-commons.yaml
559: An Operation MUST have least one Contingency Plan (CP) per Operation Volume, therefore the CP list size must be greater than or equal to the OpVol list size.

The GETTER test for tcl4valtests has a coverage leak - it is missing this business validation.
