asyncio API can be considered beta level

It's clear that there are at least many dozens of developers
working with the new asyncio extension and we have not had
any major bug reports.  Other than ``Session.delete`` needing
to be an awaitable, there were no backwards-incompatible issues
and we've seen no issues with wrong behaviors.
