[keycloak-dev] investigating caching

[Bill Burke]

I think I have a decent way of doing caching, but it is going to take a 
refactoring of the Model API and KeycloakSession API so that caching can 
be layered (i.e. that we can cache realms/apps, but not cache users). 
For instance, the JPA adapter pretty much is hard-wired to have a loaded 
entity before it makes queries like "select user where user.realm = ? 
and user.name = ?".  We need to move things like user queries up to the 
KeycloakSession level so that we can use things like 
EntityManager.getReference() so that we're not making extra DB calls if 
we need to query a user.
