[adm] introduce admin_socket.info

[gquintard]

provide an easy way for external script/programs to extract admin socket data without C bindings.

JSON output example:

[ 2, ["admin_socket.info", "-j"], 1755637539.258,
  {
    "sockets": [
      {
        "address": "::1",
        "port": 46391
      },
      {
        "address": "127.0.0.1",
        "port": 38191
      }
    ],
    "secret": "/tmp/vtc.1013468.3b74cfce/v1/_.secret"
  }
]

Non-JSON:

sockets=::1 46129,127.0.0.1 44135
secret=/tmp/vtc.1014381.62ab002d/v1/_.secret

On principle I don't like the idea, but I understand the motivation.

Maybe what we need is a standalone utility to query the VSM, a small program on top of libvarnishapi to list configuration segments.

Never mind my comment, I was certain this was a change you wanted to make in varnish enterprise.

Like #4444 I think this would be a job for varnishadm

I'll close this as really, I just need to know the workdir and I can discover all this by reading a few files
