Diag session routing (#8232)
Code to support react based UI for diagnostics:

* pprof, prometheus and diagnistics rationalized to use a single router
(i.e. they can all run in the same port)
* support_cmd updated to support node routing (was only first node)
* Multi content support in router tunnel (application/octet-stream &
appliaction/json)
* Routing requests changed from using http forms to rest + query params
* REST query requests can now be made against erigon base port and
diagnostics with the same url format/params
