Require storage directories to exist at startup
Right now GitLab tries to check if the disks are reachable, but this is not it's responsibility.
This gave a couple of options to how Gitaly would do this, and I've opted to detect at boot if the storage is reachable. A forgotten mount will be clear this way, and logged without being hidden between lots of other messages.
Closes #1341 (closed)
