**Summary** macOS tests on Travis CI keep timing out and they run very slowly. This patch attempts to solve this by doing the following: - Use ramfs for `__tests__` folder and for `$TMPDIR` for faster file system - Remove unnecessary `brew update` and `brew install yarn` commands - Remove unnecessary `--max-workers` argument since all CI VMs have only 2 cores - Clean up tmp folders per test after they are done - Fix `link/unlink` test's race condition and previous test case reliance - Fix `request-manager` timeout tests to be more reliable and finish in under our normal timeout - Use real timers by default and add necessary `useFakeTimers` calls - Increase heap size for Linux and OS X to 4 GB since OS X builds were crashing due to limited heap space - Removes retries from Travis CI **Test plan** All tests on all platforms should pass and pass in about 20 minutes max.
