Khepri 0.9.0

At this point, Khepri should be considered Beta and not production ready. The API will likely evolve and future releases will likely introduce breaking changes. The goal of this release is to make it easy for anyone to try it and possibly give feedback.

What's new in Khepri 0.9.0

This release focuses on a couple improvements and bug fixes to async commands.

Improvements to async commands

• Correctly use the cached leader ID if it is present to send the command (#228).
• Replace khepri:wait_for_async_ret/{1,2} with khepri:handle_async_ret/{1,2} (#229). The previous API didn't match the underlying Ra API. It's better for the caller to receive the message(s) from the Ra server, then call khepri:handle_async_ret/{1,2} to let Khepri do internal things such as updating the cached leader ID.

Other changes

• Expose the ?IS_KHEPRI_STORE_ID/1 macro (#231).
• Ra was bumped from 2.6.3 to 2.7.0 (#232).
