Support annotations on parameterized types

It appears that java.validation allows validation annotations to be used
on the type parameters of Collection and Map classes.  Updated the
validation code to support that.  Once policy-models has been updated to
use this approach, the original @Items and @Entries annotations will be
deprecated.
