* Enable "new-metrics" by default
This change switches the defaults between "new-metrics" and "legacy-metrics".
Now the defaults are:
- "new-metrics" ON by default
- "legacy-metrics" OFF by default
- "add-instance-id" ON by default
* Use Prometheus parser in tests
* Allow internal metrics bind address to be configurable and change to localhost:8888
This allows the internal metrics to be served on an address other than 0.0.0.0.
The new command line flag is --metrics-addr. It changes the default listen
address to be localhost so that exposing it on the network is opt-in.
* listen on localhost only for dev build
* Change census-instrumentation to open-telemetry and update authors
census-instrumentation/opencensus is now open-telemetry/opentelemetry
"OpenCensus Authors" is now "OpenTelemetry Authors"
"Copyright 2018" is now "Copyright 2019"
Fix go fmt
* Add basic telemetry to collector
This change adds a Prometheus endpoint using OC to provide metrics
to the collector. There are settings to control the level and port
in which the metrics are exposed. The main metrics added for now
are in the queued exporters.
* Check for view registration errors
