Description

While troubleshooting an out of memory error exporting snapshot to s3a, I found that ExportSnapshot doesn't close FileSystem instances it uses.

An implementation (s3a e.g.) may depend on close() call so that resources are released.
ExportSnapshot should close the FileSystem instances upon exit.
