Package adapter provides gRPC adapters between client and server gRPC interfaces without needing to go through a gRPC connection.

Package cache exports functionality for efficiently caching and mapping `RangeRequest`s to corresponding `RangeResponse`s.

HandleHealth registers health handler on '/health'.

HandleMetrics performs a GET request against etcd endpoint and returns '/metrics'.
