Does it make sense to use gzip compression for Thrift HTTP senders?

[yurishkuro]

This change https://github.com/uber/jaeger/pull/282 allows gzip, but perhaps it's only useful when submitting spans as JSON.

The linked PR is related to zipkin. I am not sure if we want to implement it in our zipkinSender. However our ZipkinSender is a wrapper around arbitrary zipkin sender so Gzip encoding could be used.

#399 will introduce zipkin reporter (v2) so that any sender could be used.

I will close it. Please reopen if this is for jaeger http sender.
