Enhance Metadata Resolution

[Rene2mt]

User Story

As a developer, I want specific assemblies within the source profile or catalog resolved in the resulting resolved profile catalog

Goals

• add ability to include responsible-party, from the source profile or catalog, using the child "keep" prop in the source metadata assemblies. Currently, only the metadata role and party assemblies carry over to the resolved metadata.
• the resolved metadata should prune the child "keep" props that came from the source profile or catalog

NOTE
Upstream OSCAL seems to have some constraints that prohibit use of the "keep" prop within metadata ,role, party, and responsible-party assemblies, so their inclusion in a profile or catalog causes validation errors.

Per discussion today with @Rene2mt, there may be some issues with filtering out prop[@name="keep"] as well in intermediate catalogs per these comments in #1184. More investigation needed. @david-waltermire, should we make a go for this in an upcoming release or backlog it for a follow-on? For now, Rene confirms we have a workaround, so we have breathing room if we need it.

@aj-stein and @Rene2mt It would be helpful if we had test metadata to excercise this functionality. Anyone interested in providing some test content?
