Changelog

Unreleased - 0.6.0

Backpressure queue size is controlled by either ZIO_GRPC_BACKPRESSURE_QUEUE_SIZE environment variable or zio_grpc.backpressure_queue_size system property (previously the names were hyphenated). Change was made for compatibility with ZIO Config.
Removed the R type parameter for generated services. Generated services now have a single type parameter for context. This simplifies the previous APIs and encourages the ZIO 2 style that service dependencies are passed via constructors (see service pattern)
Context is now received as a second parameter for each handler. For convenience, there is a trait that only takes one parameter (the request type).
Simplified ZTransform. Introduce Transform for effectful transformations for services that do not have context.
Classes and methods with suffix ClientWithMetadata have been renamed to ClientWithResponseMetadata.
Removed the R type parameter in most APIs.
ManagedServer renamed to ScopedServer.
Clean shutdown when a server is ran through a Scope or ZLayer.
Added backpressure support docs

Signifcant server performance improvement (2.4x faster handling) (#457)
Server can now send response metadata (#418)
Clients can now access the response metadata sent by server (#428)
ServiceList now has a provideLayer and provide that can be used to satisfy services dependencies.
