Release 1.2

[2opremio]

@davkal @foot @ekimekim @bowenli @jpellizzari @tomwilkie @abuehrle @pidster @errordeveloper @rade Please chip in by testing this release branch in the scenarios below and tick off what you tested afterwards (including your name at the end). Have a look at the CHANGELOG to prioritize your testing.

To make things easier to test I have pushed the image weaveworks/scope:release-1.2-9e33e7e
Thanks!

@simon found #2207, #2208 and #2209. I think #2207 and #2209 should be fixed before the release.

I updated the probes in WeaveCloud dev to run weaveworks/scope:release-1.2-9e33e7e and I don't see any regressions in CPU performance.

It's not great (50% CPU) but better than 1.0 (#1985 (comment) )

[abuehrle]

I am just upgrading my environment with scope: scope:release-1.2-9e33e7e

Note also that there was an issue with Zipkin (tracer for microservices demo) hogging a fair share of resources as well: microservices-demo/microservices-demo#598

[2opremio]

Fixes #2216 (doing it here since there is no better way to test it than during a release itself)

[jpellizzari]

LGTM!
