Target agents based on agent version

A little similar to https://github.com/buildkite/feedback/issues/229 however the targeting would be based on the buildkite agent version. Perhaps this is available already… I couldn’t see it.

In your steps you could have:

agent:
   version: '>3.0'

or version: '^3.0'

You don’t need to define any tags when you start the agent. They’re already built in.

You could combine queue and version.

agent:
  queue: 'ruby'
  version: '^3.0'

This is useful if we use plugins but still have some agents ‘~2.0’
