Check if all the memcached servers in a cluster are responding.
 The memcache cluster to check is specified with the <tt>:cache</tt> options. The
 value can be either a Dalli::Client object (from the dalli gem) or an
 ActiveSupport::Cache::DalliStore (i.e. Rails.cache).

 If making the IP addresses of the memcache servers known to the world could
 pose a security risk because they are not on a private network behind a firewall,
 you can provide the <tt>:alias</tt> option to change the host names that are reported.

 === Example

   IsItWorking::Handler.new do |h|
     h.check :dalli, :cache => Rails.cache, :alias => "memcache server"
   end
