Implement command to list running Firecracker MicroVMs in Pool

Context

There's no way to list MicroVMs apart from looking at ps auxfw, ip netns ls or similar output. It would be nice to see them using fireactions ls <POOL NAME> or similar command.

Possible Implementation

1. Get all VMs from Pool
2. Print them out to the terminal

Hopefully I can work on this tomorrow

@konradasb do we intend to:

• parse ps output
• rely on filesystem where firecracker runs or
• have an external state about pools?

Im trying to understand what possible inputs we could use

[konradasb]

Essentially, we keep a list of running MicroVMs inside a Pool here. The command should send HTTP request for listing MicroVMs of a specific pool.
