Transfer an OD instance to Spot to send an ITN

If a user is testing their application's spot handling on an OD instance, it would be useful to transfer the VM to a spot instance since FIS will only send an ITN to the Spot instance. We should explore hibernating and transferring the EBS volume to the same instance type but with a spot purchasing option.

```
$ ec2-spot-interrupter -i i-0123456789
⛔️ i-0123456789 is an on-demand instance
Would you like to hibernate and launch on a spot instance (y/n): y
Hibernating i-0123456789
Launching Spot instance i-9876543210
Sending Spot ITN
```

Start with the ec2-spot-interrupter CLI flow shown in the issue and inspect how it handles an on-demand instance. Define the hibernation, same-type Spot launch, EBS transfer, and Spot ITN steps, then verify the command produces the illustrated outcome for an instance ID.
