Summary

This is the proposal for the first phase of the Ruby SDK. This is the second discussion of this proposal, see #92 for past discussion.
See it rendered.
Much of this is inspired by the current Temporal Ruby SDK (and its proposals which were moved to a sub directory) and our other SDKs.
Use this PR for comments/discussion. Don't be afraid of making too many comments; if it gets too noisy, I'll just create another PR.
Any points of contention will be discussed in-person by the SDK team and a decision will be made.

For the public, please also join us on #ruby-sdk in Slack.
