Select local instance ID automatically

If the user creates an instance with --local-instance without the ID,
acloud selects an unused instance directory. Each directory is guarded
by a lock file, so the testing infrastructure can run multiple acloud
processes in parallel.

This commits also removes IsLocalImageOccupied to simplify the logic.

Test: acloud-py3-dev create --local-instance --local-image
Test: acloud-py3-dev delete --local-only
