Support large-scale bulk change due date

Purpose: Renewals for hundreds of items, or changing the due date for hundreds of items, are failing after 99 items. Back end work is needed to support bulk actions for hundreds of loans at a time.

from yevhenii_maltsev:
There are 2 individual requests (1 OPTIONS, 1 PUT) to renew every loan, so there are too many requests to renew the list of loans. In the case of snapshot or test env, it's really challenging to do it without errors and not to drop down the service (because it takes a lot of resources to handle them). So it seems, the special endpoint on the backend should be created to renew (and change due date) the bunch of loans.
