Pete Richards 8db75bf41e [API] Support dynamic telemetry metadata (#1941)
* [API] Support dynamic telemetry metadata

Add support for dynamic telemetry metadata via custom telemetry
metadata providers.  

The metadata provider API should be considered unstable in it's
current invocation.

* Perform deprecation checking at runtime
* SWG uses telemetry metadata provider
* Don't throw with no matched metadata provider
* Update API docs
* Add license header
* Combine metadata providers with general telemetry providers
* Replace `TelemetryAPI.canProvideTelemetry` with
`TelemetryAPI.isTelemetryObject`.  
* CanProvideTelemetry is deprecated
* Change SWG inputs to numberfield
