Describe the current behavior

abra app ls -S explodes with 15 ssh host key checks.

Steps to reproduce

rm ~/.ssh/known_hosts && abra app ls -S

Describe the expected behavior

It works. Servers get listed.

Any idea how this might be fixed?

I think we need to teach abra itself how to do host key checks or potentially more unstable, pass no host key check option when making SSH connections and warn folks that this is the case.

This does make it all Just Work ™️

This would be easiest for us....

Will investigate making abra manage host key checking itself also.
