Fix snapshot reload on ec2 instances (#298)

Apparently, AWS has patched its base utils, which works differently when we try to use our scripts.
In this particular case, their ls utility doesn't support a [real basic] flag -l. This caused our reload
script to crash without reloading the subscripts for each particular volume that is tracked by the
driver.

Closes #297
