[ENG-6265] supplementary metadata

[aaxelb]

allow "supplementary" metadata records

• declared by adding a is_supplementary query param (regardless of value) to a POST to /trove/ingest
• added to all pre-existing index-cards from the same user with the same focus_iri (if any)
• will not get an index-card of its own
• will not affect the last-updated timestamp (e.g. in OAI-PMH) of the index-cards it supplements (<== this is the main point -- allows indexing monthly-computed metrics and system-specific administrative metadata without triggering full re-harvests every month)

I'm not seeing a CR on this. Do we need to accelerate getting you help on SHARE? Getting folks doing CR might be a good way to start.

@brianjgeiger it was reviewed by @felliott in a call we had together, going thru each change and discussing what/why -- agree doing review together is a good way to share share knowledge, but will be sure to leave a comment (or harangue for actual github approval) when doing that in the future

@aaxelb Awesome, thank you. And thank you @felliott for the assistance.
