dashboard/dashapi: retry requests on errors
API requests episodically fail due to internal datastore errors, some timeouts, etc.
Failure of some requests is especially unpleasant and leads to lots of wasted work
(uploading of syz-ci build info, job completion, etc). So we retry requests
several times. We do this always for all requests, since we don't expect any of them
to legitimately fail (we don't send malformed requests), and it won't harm for any
request types.
