Manage a pool of nodes for a distributed test infrastructure

Clark Boylan cb1860565f Have nodepool scan as many ssh host keys as possible
We are seeing users try to enable fips on their test nodes. This
presents a problem because the ssh host key which we've been using is a
ed25519 key which fips disables. Fips forces the use of another key
which ansible doesn't trust and subsequent ssh connections fail.

Address this by trying to scan all available host keys on the server and
not just the first one that paramiko returns.
