Issue MULE-8177: HttpListener ParameterMap should behave as a Map
ParameterMap is a Map and holds the values of query parameters, uri parameters and POST params. The problem that currently have are: - The parameter map is mutable when it should't - It does not have an API in the interface that can be used by the user (there's an special method getAll used when a parameter returns a collection of values) - it does not comply with the Map interface for Map as it declares.
