Move fibers out of experimental

Summary: folly::fibers have been used by mcrouter for more than 2 years, so not really experimental.

<p>First fiber-task will grab a lock and then suspend waiting on a <tt>fibers::Baton</tt>. Then second fiber-task will be run and it will try to grab a lock.

<p>There&#039;re generally two ways we can solve this problem. Ideally we would re-design the program to never not hold any locks when fiber-task is suspended. However if we are absolutely sure we need that lock - folly::fibers library provides some fiber-task-aware lock implementations (e.g.
