Fix "Listening on" log message

[mkouba]

• resolves Customized quarkus.http.host not reflected in "Listening on" log message #1044 and Wrong port reported in the logged messages #815

The log message now looks like:

Quarkus 1.0.0.Alpha1-SNAPSHOT started in 0.589s. Listening on: http://127.0.0.1:8080

That first one looks a bit funny; if we insist on rendering these things as URLs we should definitely use org.wildfly.common.net.Inet#toURLString(java.net.InetAddress, boolean). It would render the above as [::] instead of the much uglier (and anyway invalid, at least in a URL) 0:0:0:0:0:0:0:0.

@dmlloyd Do you want that change to use Inet#toURLString(java.net.InetAddress, boolean before merging this?

[dmlloyd]

Yeah let's fix that, so the URLs are at least valid.

[starksm64]

@mkouba Martin, and you add that change so I can merge this?

[starksm64]

So this line should be:
address = Inet.toURLString(addr, true) + ":" + inetAddress.getPort();
