Devin Petersohn a174a46e02 Allowing multiple users to access the /tmp/ray file at the same time (#3591)
* Allowing multiple users to access the /tmp/ray file at the same time

Previous sequence that caused this issue:
* User A starts ray with `ray.init` when /tmp/ray does not exist
* User B starts ray with `ray.init` and /tmp/ray now exists

User B will get a permissions error
Checking the permissions, /tmp/ray is 700

I have identified a race condition in `try_to_create_directory`
* Multiple processes try to create /tmp/ray at the same time
* chmod is either silently erroring or working properly within the race condition

Resolution: Move chmod outside of the check for whether the directory exists or not.

* Adding try except for users who do not own the directory
