Test for forever-agent PR #29 - Enable socket reuse

Added as requested by @simov

Looks like the error is that the test failed. The forever-agent PR #29 is needed for the test to succeed.

@mgorczyca thanks for your input. However your test is failing only on 0.10, and it is passing with 0.12 and io.js without applying your fix from the forever-agent repo. The error you are seeing in TravisCI is that the next test is timing out, which is completely different issue. Just skip the next test tape.skip and run tape tests/test-agent.js with both 0.12 and iojs - you'll see that your test is passing, so I'm not sure what exactly it tests.

Thanks for your feedback @simov. I thought I had run my test in a pure 0.12 environment, and discovered one override to 0.10. I originally discovered the problem in 0.10 where the test still (properly) fails. Once I corrected my 0.12 environment, the test passes there for me, just as it does for you. We are planning to use 0.12 at this point, so we can close the issue and the PR if you agree that is best.

Closing in favor of #1671 - request now defaults to http(s).Agent in node 0.12+ when the forever option is used.
