Add test to verify instance bootability after volume snapshot

Browse Source 
This patch adds a test to ensure an instance can boot
from a bootable volume after a snapshot is created while
the instance is in a stopped state. The issue being
validated impacts volumes that use an NFS backend,
causing boot failures post-snapshot creation.
