zetaclient status: 8123 http server

[brewmaster012]

in v16 the 8123 http server data were bundled into prometheus telemetry. This breaks a3-console.

I request this to bring back (keep the data in prometheus as well, just restore the old port 8123 http server functionality).

bundled in this PR #1885

will pick this one up to revert changes and keep metrics that were added in that PR
