This changes the internally used names for entities and entity values when
sent on the messagebus and used interanally in the intent service from start / end to entity_value and entity_type.
This makes the terminology easier to understand and follow across into Adapt.
The old terms are still included and usable for compatibility but should be
removed in an upcoming major release (22.02).
- Remove unused ContextManager import from mycroft.skills.intent_service
- Remove Old 'intent_failure' -> fallback handler
- Remove handling of fallback messages without the fallback_range
parameter
Remove the use of the separate error message and use the wait_for_reply method
to get the converse result. The error message is left to guarantee
compatibility.
