Integration with SmokeDetector and Metasmoke

[thesecretmaster]

Here's a list of changes that need to be built into Metasmoke or SmokeDetector to make them compatible with Helios:

SmokeDetector:

• Notifications
  • Keeps cache of notifications from Helios, reloads cache when it becomes active
  • Pushes new notifications to its cache and to Helios and sends a message to Metasmoke over the websocket (format TBD)
  • New command to kick cache
• Black/Watch listing
  • Pushes black/watch list requests to Metasmoke over websocket (Format TBD)
    • Falls back to pushing black/watch list requests from privileged users to Helios
    • Shows error when Metasmoke is down and an unprivileged user attempts to edit the black/watch list
  • Keeps cache of black/watch list items from Helios, reloads cache when it becomes active
  • Post a message when a black/watch list item is approved (will receive a WS message from Metasmoke, format TBD)
  • New command to kick cache

Metasmoke:

• Notifications
  • UI for viewing/editing
  • Cache which can be refreshed from Helios on button click
  • Can push items to cache when receiving a message on it's websocket to Smokey
• Black/Watch listing
  • Recieve black/watch list requests from SmokeDetector (push to Helios if privileged, otherwise add to pending list)
  • UI for approving black/watch list requests
    • On approval push to Helios and send WS message to smokey
  • Cache can be refreshed with a button click
  • Send invalidation (or probably "please check this key again") notice to Helios at appropriate time when a SmokeDetector key is revoked / removed.

SmokeDetector/Metasmoke new websocket messages (format TBD):

• MS -> SD Black/watch list item has been approved (reply "message posted")
• SD -> MS New black/watch list item (reply "success")
• SD -> MS New notification (reply "success")
• MS -> SD Kick watch/black list / notification cache (reply "success")

Some questions:

Could Helios have some endpoint which gives changes since ?
On the MS/SD websockets, is there usually a "success" reply?

Looks good to me, @AWegnerGitHub and maybe @quartata would know more about blacklisting details.

Edited to add sending a notice to Helios when a token gets invalidated.
