  1. Add lockfile at snapshot activation to avoid race condition 

    This creates an ignite lock file at /tmp/ignite-snapshot.lock
when an overlay snapshot is created. The locking is handled via
pid file using github.com/nightlyone/lockfile package. This
helps avoid the race condition when multiple ignite processes try
to create loop device and use the device mapper for overlay
snapshot at the same time. When a process obtains a lock, other
processes retry to obtain a lock, until a lock is obtained. Once
the snapshot is activated, the lock is released.
