all: implement API to remove all caches

On the HTTP side, if the query parameter "name" for "DELETE /api/caches"
is "all" it will remove all caches.

On the resolver side, if the parameter for "caches remove" is "all"
it will remove all caches.

This changes require latest lib/dns on share module.
