Add proxy user to requests

thanks, that is helpful

Certain users (such as professors) authorize other users (such as research assistants) to do things on their behalf. Commonly, that means borrowing items on their behalf, which is why we implemented check out as proxy. But it can also mean making requests for items on their behalf. So we need to support request by proxy (). We also want to display the name of the requesting proxy in the Requests search results, when applicable (). There is so far no requirement to search by proxy.

I think the percentage of requests made by proxies is pretty small. Probably less than 10%.

what functionality will the proxy be used for? is it for searching? how many requests are we talking about? i am asking because we need to understand when adding a field its use cases (from a DB standpoint as well , indexes...)
