consider adding a wait option

REMS is a synchronous application, and sometimes it is running slow, and getting too many updates back to back will result in a DB conflict.

Consider adding an argument for a custom length wait between each HTTP POST request.

No files or tests are named. Start by locating the loop that sends HTTP POST requests and the argument-parsing entry point; add a configurable wait between requests, then verify that copied items are still sent correctly with and without the option.
