Add provenance tracking for V2

[jsuereth]

This adds the provenance tracking we had discussed during our list SIG.

• Weaver Resolved schema will track the following:
  • The whole schema has a list of dependencies, which are schema_urls
  • Every attribute in the catalog has a Provenance which will include a reference to the index of the dependency that defined it.
  • Every signal / attribute group will have the same Provenance.
  • Any attribute / signal defined locally to the schema (i.e. not imported) will NOT have a Provenance.
• This does NOT impact "forge" / template schema yet, that will be follow-on work and we may want to discuss what belongs in forge.
