Title: Deprecate autotest support in 2.99

This will print a `Kernel.warn` line after each run of an rspec suite if someone isn't using `rspec-autotest`

I choose to deprecate this with a naked warn because otherwise I'd have to load parts of `rspec-core` into the autotest runner, which seemed unnecessary compared to a simple warning...
