add adapt match levels

[emphasize]

Problem: The Adapt matcher matching unrestricted.

As with the other services, 3 (configurable) threshold matcher are added to the pipeline for finegrained adjustability.
One thing in question, is the config option (key context) what we want?

Companion PR (config): OpenVoiceOS/ovos-config#100

[emphasize]

the rest of the failing unittest should go back to the config defaults in ovos-config
