AnyValue

[obecny]

Steps to reproduce

1. Get latest version for example 71392e5d543eca6e895d852c9bad122b18ae7b23
2. Try to send span with attributes converted to latest proto format using AnyValue for example

{ key: 'service.name', value: { stringValue: 'basic-service' } }

What did you expect to see?
I expect to see the span in zipkin

What did you see instead?

1. For grpc it works fine
2. For json over http it doesn't
3. For proto over http it doesn't

WIth latest docker 0.6.0. (just released) and changes in configuration I was able to test this correctly;
