JSON Reply Management API - feature parity with old management interfaces (#861)
* Ensure that recent code additions pass the linter

* Include some of the more obviously correct lint fixes to edge_utils.c

* Refactor edge JSON api into its own source file

* Use shorter names for static management functions

* Implement a JSON RPC way of managing the verbosity

* Tidy up help display in n2nctl script

* Make note of issue with implementing the stop command

* Implement a JSON RPC call to fetch current community

* Make n2nhttpd time value be more self-contained

* Make n2nhttpd order more closely match the existing management stats output

* Wire up status page to the verbosity setting

* Add JSON versions of the remainder of the edge management stats

* Add new file to cmake

* Properly define management handler

* Only update the last updated timestamp after a successful data fetch

* Function and types definition cleanup

* Force correct type for python scripts mgmt port

* Implement initial JSON API for supernode

* Fix whitespace error

* Use helper function for rendering peers ip4 address

* Proxy the auth requirement back out to the http client, allowing normal http auth to be used

* Ensure that we do not leak the federation community

* Use the same rpc method name and output for both edge and supernode for peers/edges

* Allow n2nctl to show raw data returned without resorting to tricks

* Make n2nctl pretty printer understandable with an empty table

* Use the full name for supernodes RPC call

* Use same RPC method name (but some missing fields) for getting communities from both edge and supernode

* Add *_sup_broadcast stats to edge packet stats output

* Refacter the stats into a packetstats method for supernode RPC

* Even if I am not going to prettyprint the timestamps, at least make all the timestamps on the page the same unit

* Simplify the RPC handlers by flagging some as writable and checking that in the multiplexer

* Remove invalid edges data

* Avoid crash on bad data to verbose RPC

* Avoid showing bad or inconsistant protocol data in communities RPC

* Minor clarification on when --write is handled

* Make linter happy

* Fix changed method name in n2nhttpd

* Move mainloop stop flag into the n2n_edge_t structure, allowing access from management commands

* Implement edge RPC stop command

* Move mainloop stop flag into the n2n_sn_t structure, allowing access from management commands

* Implement supernode RPC stop command

* Allow multiple pages to be served from mini httpd

* Extract common script functions into a separate URL

* Handle an edge case in the python rpc class

With a proper tag-based demultiplexer, this case should be a nop,
but we are single-threaded and rely on the packet ordering in this
library.

* Add n2nhttpd support to query supernode using urls prefixed with /supernode/

* Handle missing values in javascript table print

* Add another less filtering javascript key/value renderer

* Add a supernode.html page to the n2nhttpd

* Address lint issue

* Mention the second html page on the Scripts doc

* Remove purgable column from supernode edges list - it looks like it is rarely going to be set

* Add a simple one-line example command at the top of the API documentation

* Acknowledge that this is not the most efficient protocol, but point out that it was not supposed to be

* Make it clear that the n2nctl script works for both edge and supernode

* Fight with inconsistant github runner results

* Turn off the /right/ coverage generator
