text: Title: [Telemetry] Move telemetry-tools fixtures into package
  Body: The telemetry tools package uses fixtures in `src/fixtures/telemetry_collectors`.
  
  These fixtures are using the telemetry plugin `collectorSet` thus why the files lived inside `src` rather than inside `packages/kbn-telemetry-tools`.
  
  Since the tool parses the files statically we can `@ts-ignore` the fixture files and move them into the package.
  
  The `telemetry_collectors` folder is the only folder in `src/fixtures/` so moving it makes sense to reduce surface area of `src`.
