BUG/MINOR: dns: Fix CLI keyword declaration

The cli command to show resolvers stats is in conflict with the command to show
proxies and servers stats. When you use the command "show stat resolvers [id]",
instead of printing stats about resolvers, you get the stats about all proxies
and servers.

Now, to avoid conflict, to print resolvers stats, you must use the following
command:

     show resolvers [id]

This patch must be backported in 1.7.
