v1.2.0

This release adds HTTP/2 and compression support.

All CodeArtifact communication (direct, or via a CDN) now uses the OkHttp client for communication, negotiating HTTP/2 and allowing for compression of responses (for compressible types, such as Gradle module metadata and POM files).

When combined with the CDN/proxy feature the speedup for artifact downloads can be 50%+ (with higher improvements where the network distance/latency from CodeArtifact is greater).
