d79a99323e make .get_current_user async

- use `.current_user` to access current user in methods
- adds Authenticator.refresh_user for refreshing user auth (unused at this point)

373c3f82dd SSL setup for testing 
Setup general ssl request, not just to api

Basic tests comprised of non-ssl test copies

Create the context only when request is http

Refactor ssl key, cert, ca names

Configure the AsyncHTTPClient at app start

Change tests to import existing ones with ssl on

Override __new__ in MockHub to turn on SSL

707b300bd6 add iterate_until utility 
allows iterating through an async generator, yielding items until another Future resolves

if/when that deadline Future resolves, ready items will continue to be yielded until there is one that actually needs to wait
at which point the iteration will halt

fd40e27be4 indicate that REST API timestamps are UTC 
use iso8601 Z suffix for UTC timestamps

use dateutil to parse dates from proxy, as well

even though CHP uses iso8601 UTC timestamps, we no longer assume CHP, so use more general parsing

in our db we are stuck with naïve datetime objects, so use those internally.
But ensure we put 'Z' on timestamps we ship externally

8de38b1708 add some jitter to the deadline itself 
so that we don't re-align a bunch of timing out calls once the deadline is reached.

6db987972a exponential backoff 
- apply jitter to first iteration
- due to jitter, double start_wait to 0.2 so that <first wait> is still 0.1
- keep scaling by start_wait, rather than previous dt
- limit last wait to deadline so timeout is not overshot

8e3c4b1925 apply exponential backoff to all waits 
Waiting for servers to come up and shut down was polled at an even interval of 100ms. If things are slow and busy, this is a lot if waiting events. exponential backoff reduces the number of callbacks triggered by slow spawners.

This may improve the load a bit when there’s a bunch of outstanding spawns.
