* drop stack driver as a tracing backend
* drop stackdriver as a metrics backend
* update deps - dropping stackdriver
* fix linting issues
* drop further references to stack driver
* drop serving & eventing metric key constants
these have been moved to their respective repos
see: https://github.com/knative/pkg/issues/608
* move source metrickeys to pkg/source
We're going to move the StatsReporter downstream eventually

* fix linter
We currently keep all metrics exporters created since start.
For a busy, long running server, this will be a problem. Clean
these up when they get old so we don't dedicate memory to non-existent
* Use real synchronization to make sure we get four exports in the OpenCensus test.
* Fix a few bugs in the metrics implementation:
1. We could create two OpenCensus exporters for the empty resource, which would cause double-reporting
2. Add a mechanism to clear out background Meter threads to to prevent them exporting in subsequent tests.
* Make sure metrics tests are re-entrant
Currently they are not. 'go test -count=2' will miserably fail.
So ensure they are. Also add a helper to return current value.
* review
* Make EnsureRecorded part of metricstest; call it automatically in the "Assert" methods.
Increase test coverage.
* Address yanweiguo comments
* Add a barrier to ensure all metrics are recorded before scraping prometheus.
* Add component name as the metric prefix for opencensus exporter
Read from all meters instead of just he default one
Add component name as the metric prefix for opencensus exporter
* Update codegen
* Add domain as metric prefix
* Use path.Join to simply the code
* Update OpenCensus to include #1196.
* Extend OpenCensus to track per-Resource stats.
* Add generic ResourceView mechanics, part 1. TODO: wire newFactory, tests
* Move factory creation to where it can be customized per-backend
* Integrate opencensus export with Resource-based exporters
* Add stackdriver support for resource views
* address feedbacks
* add test cases
* make KnativeRevision a map
* Update go modules to point to latest opencensus which includes `view.Meter`.
* Add support for Resources to Prometheus Exporter.
This involved copying/improving much of the contrib prometheus exporter.
* add resource_view tests and fix minor issues
* add recorder tests for meter
* Update resource_view_test with an e2e export test.
* Fix prometheus e2e resource_view_test.
Found a fun circular lock.
Found a fun double-registration in metricproducer/Meter.
Found some unnecessary extra code.
Fixed prometheus string sanitization.
Removed a layer of Prometheus wrapping which made debugging more challenging.
* Add test for standard view exports and non-resourced views to e2e test.
* Add UnregisterResourceView to fix tests
* Add OpenCensus e2e resource export test.
Still a little flaky, so work around that with "<=".
* Fix tests for OpenCensus export.
* Fix flakiness / timing issues in OpenCensus exporter e2e test.
* Update to latest ocagent to fix `Resources` bug.
* Don't swallow errors from stackdriver init.
* Get Stackdriver export mostly working in e2e tests
Tests still fail because stackdriver converts custom metrics to a namespaced format and seems to lose Resource information.
* Add support for Stackdriver resource export.
* ./hack/update-codegen.sh
* Fix data race with graceful shutdown.
* Fix issues noticed by @vagababov
* Address mattmoor-bot comments.
* Remove MonitoredResource and apply suggestions from yanweiguo
* More cleanup to stackdriver_exporter_test.go
* Update tests (particularly config_test.go) for Stackdriver recorder changes which sometimes record with additional resources.
* Avoid setting two `view.WithRecorder` options on record
* Add stackdriver tests
* Address comments
* Switch Prometheus port due to possible conflict in test env
* Fix missing :=
* FIx data races around *view.Data shared across Meters.
Cleanup resource_view_test.
* Remove unneeded monitored_resources.go
* Use sync.WaitGroup to avoid data races on closing channel.
* Sort the map for ResourceAsString
* Apply lint and vagababov changes.
* Fix typos
* refactor ResourceAsString
* Update stackdriver exporter version
* Update metrics/resource_view_test.go
Remove accidental paste
* Fix go.sum
* Address yanweiguo comments on comments
* Fix autogen/go mod
* Handling resource extraction when custom metrics are allowed
* Add tests for AllowCustomMetrics set to true
* Address vagababov and yanweiguo comments.
