Support of get_property in property assignment

Refactors the current way store a get_input function allowing
to support different get functions (get_property in this case).
The information stored allows recreating and correctly validating
the get function.
Fix get function schema validation, the schema was being ignored.
Improve validation error status and messages.
Improve tosca get function dialog.
