remote/performance: add gzip compression to HTTP remote cache

[buchgr]

The Apache client supported gzip, but the new Netty client doesn't.

Let's also add Content-Type: application/octet-stream. I noticed the newer objects in my GCS bucket do not have this set either.

I'd like to make little patches to implement this as it blocks me now.

It seems like it is pretty easy :)

@excitoon That might help for some cache backends, but for people on say, Google Cloud Storage as their cache backend, it does not do compressive transcoding (this would be very expensive with respect to CPU time). What Jakob and I were discussing offline was a scheme to store compressed blobs in GCS, and then detect and decompress them in the bazel client.

Yep, I know about buchgr/bazel-remote#12 , this is just a client-side thing. Anyway, it is at least a progress on this task!
