The health-check should be implemented as an MBean initially, with the 
ability to expose it via alternative implementations later. The server 
RESTful endpoint should be registered with the management interface via 
a special handler.
A cache and cachemanager's health is determined by a combination of 
parameters and we probably should allow for a user-pluggable checker. We 
already expose a number of statuses already, although obviously this 
would be an aggregate.

I wouldn't want this to be overly complex: a simple OK, KO should be 
sufficient. Additional detail may be optionally present, but not a 
requirement.
