CE-2090: convert useRenewToken, remove legacy api provider

• converts the useRenewToken hook to common
• finishes removing all the legacy api context / files

Closes CE-2090, CE-2107

requested review from @alexandermadsen, @domonkosgulyas, and @imretoth

assigned to @christinajenks

Semi-related: the reason I had trouble with this was because I spent so much time digging in the trenches on the other bugs that I missed a simple typo: const {client} = useContext(apiContext) should have been const client = useContext(apiContext). Also, the UserProvider and many tests were using the legacy context instead of the correct one.

So, no big problems or anything at all...just a fried brain and minor typos here and there.

LGTM
