get_attributes() will only return the attributes with the pre-defined attribute type

[djs0109]

The get_attribute() method of ContextEntity only returns the attributes with the pre-defined attribute type.

Expectation
I can understand the idea behind the current behavior. But since Orion and NamedContextAttribute of filip does not validate the data type against the pre-defined data types, I would expect a method that can return all attributes to me, regardless of the attribute types.

Use Case
For example, all the auto-provisioned inexplicit attributes will have the attribute type string (not the pre-defined Text or Number). It might be a bug of IoTagent, but with the current behavior we can not get a list of such attributes.
