New Control Panel API

[stackdump]

The existing control pane was removed in the Wax build.

It needs to be replaced w/ a new Admin Panel API

Eventually, we will adopt a javascript component library for Inc's Explorer so we will need to develop a POC for how this front end will work.

Steps:

• Create a new Control panel API
  • Async: It should have a browser-side event feed component were the UI monitors events from factomd maybe making use of https://github.com/alexandrevicenzi/go-sse ?
  • Synchronous: It may have a REST or similar type of synchronous api ( maybe graphQL is suitable? ) to handle synchronous calls for info
• Integrate w/ new 'internal' pubsub framework
  • to monitor changes from various parts of the system
  • should allow for Admin user to dynamically subscribe/unsubscribe from any publisher

TODO: will add more notes about PubSub

Existing PubSub components use events are defined here https://github.com/FactomProject/factomd/blob/FD-1259_control_panel_rewrite/modules/event/event.go

FD-1259_control_panel_rewrite is the branch to use as a starting place

@Emyrk @factom-clay adding a note here

I think our understanding of how much is usable via pub/sub vs a synchronous query is evolving

we have a very simple/primitive directory to add hooks to query different objects in the new query architecture

Query module: https://github.com/FactomProject/factomd/blob/FD-1268_election_pubsub_integration/modules/query/query.go Registered in the Elections constructor https://github.com/FactomProject/factomd/blob/FD-1268_election_pubsub_integration/elections/elections.go#L62 used by diagnostic api : https://github.com/FactomProject/factomd/blob/FD-1268_election_pubsub_integration/wsapi/wsapiV2.go#L1582 (edited)

Work-in progress from BIF was merged into wax.

Control panel in WAX build is still incomplete, but the framework in place shows how to make use of Server Send Events :1st_place_medal:

New control panel won't be in Wax, we are trying to reduce the scope of Wax to get it out.
