Factor out code for starting new processes and test plasma store in valgrind. (#3824)

Browse Source 
* Factor out starting Ray processes.

* Detect flags through environment variables.

* Return ProcessInfo from start_ray_process.

* Print valgrind errors at exit.

* Test valgrind in travis.

* Some valgrind fixes.

* Undo raylet monitor change.

* Only test plasma store in valgrind.
