Improve server log startup message

[areveny]

Old output

dist % ./toxiproxy-server
INFO[0000] API HTTP server starting                      host=localhost port=8474 version=git

New output

dist % ./toxiproxy-server
INFO[0000] Toxiproxy HTTP server is starting             host=localhost port=8474 version=git
INFO[0000] Toxiproxy has started. Verify with `curl localhost:8474/version`

Closes #228

Hi @areveny

Thank you for contribution. I have not seen in other application explanation how to use health endpoint. I would avoid write this in the logs.

The application should crash if there is some problems. Also I think the second message does not correctly says that server hast started listen for the port. But it was executed just write after the first message.

I would keep only one message:

INFO[0000] Starting HTTP server on endpoint localhost:8474   host=localhost port=8474 version=git

The basic verification that it is working:

$ toxiproxy-cli list

INFO[0000] Toxiproxy HTTP server starting on endpoint localhost:8474  host=localhost port=8474 version=git

Sounds good, here's the updated output. Do you think this closes the linked issue? Or should the documentation be updated.

It is fine just to close the linked issue. The endpoint to check if toxiproxy ready is presented in README.

dist % ./toxiproxy-server
INFO[0000] Starting HTTP server on endpoint localhost:8474  host=localhost port=8474 version=git

Thanks. It's now what you suggested. Really appreciate the feedback on a small change, I hope I can make more substantial contributions too.
