A constraint that checks the permissions of a subject (if using {@link PatternType#EQUALITY} or {@link PatternType#REGEX}) or
{@link be.objectify.deadbolt.java.DynamicResourceHandler#checkPermission(String, Optional, DeadboltHandler, Http.RequestHeader)} (if
using {@link PatternType#CUSTOM}).

@param value       the constraint value
@param patternType the type of pattern matching
@return a function that wraps the constraint
