Re-enable opencensus python (#103)

Browse source 
Enables tracing in the email and recommendation services, which was disabled in 316db88 because of a memory leak in the stackdriver exporter.

We fixed the leak in https://github.com/googleapis/google-cloud-python/pull/6856. The fix is included in the [0.1.10 release of opencensus-python](https://github.com/census-instrumentation/opencensus-python/releases/tag/v0.1.10).

With this diff, traces show up as expected in stackdriver while running the demo on GKE. Using an `opencensus-python` package version before `0.1.10` causes the email and recommendation services to leak memory until they OOM. Memory use is back to normal (i.e. roughly constant) using the new package version.
