[2/3] incubator-brooklyn git commit: Remove catalog item parameters in line with type registry changes

Posted by he...@apache.org.
Remove catalog item parameters in line with type registry changes

The parameters are still populated in the spec, it's just the catalog item that doesn't have the API to get the parameters. Also fixes another shortcoming where parameters in catalog items were eagerly evaluated, not updating if dependant catalog items changed.

+Entities, policies, and initializers may accept additional key-value pairs,
 usually documented in their documentation (e.g. javadoc), or in the case of Java
 often as static fields in the underlying Java class.
 Often there are config keys or flags (indicated by `@SetFromFlag`) declared on the class; 
 these declared flags and config keys may be passed in at the root of the `ServiceSpecification` or in `brooklyn.config`.
 (Undeclared config is only accepted in the `brooklyn.config` map.)
+Referencing the parameters from within java classes is identical to using config keys. In yaml it's
+usually referenced using `$brooklyn:scopeRoot().config("displayName")`. See below for more details on scopes.
