* 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

* Add RecordN method to permit recording of N measurements simultaneously.
In serving we have many places where we try to record several metrics at the same time.
Besides very repetetive code, this also brings inefficiences, since metrics code has to do _some_ work
for every call, which is completely avoidable.
This way we can record N measurements with one hit.
* tests and nits
* review items per discussion with Evan:
- remove ros
- make measurements ...
* review
* Add metrics to webhook package
Add metricstest package for shared helper functions for testing metrics
* Address PR
* Cleanup
* Fix import paths to fix build issues
* Fix import package path for test file
* Remove unnecessary formatting from error message
* Remove helper function only used once
* Add metric name to all error messages, make checkRowTags testing helper function
* Add common histogram bucket generator function to metrics package
* Fix CheckStatsNotReported check
* Reset metrics before each test so the tests are idempotent
* Make CheckStatsNotReported conditional clearer
* split and update
* bug fixed
* change the copyright year
* use fake metadata in tests
* exclude test coverage for gcp_metadata
* add record
* add tests
* revert 2019 and add a new var
* change documents
