 Problem: to enable resolver, the normal steps are: start bind10 (including
 auth server); use bindctl to configure bind10 to start resokver instead;
 stop bind10; start bind10 again (includes resolver); use bindctl to
 configure resolver to listen on correct interface/port, do forwarding,
 etc. (because couldn't be configured before).

 Workaround: just like bind10 and b10-auth has -a and -p options for auth
 address and port, bind10 should have command-line options to choose
 address/port/forwarder and to enable the resolver too. b10-resolver could
 also have command line options for these too.

 Note that an early version of the resolver did have some command-line
 options. Now they are gone. This is inconsistent with b10-auth.
