list known names (if any) for new hostkeys

When connecting to a host for which there's no known hostkey, check if
the new key has been accepted for other hostnames.  This is useful when
connecting to a host with a dynamic IP address or multiple names.

--- Comment #1 from Damien Miller <djm at mindrot.org> ---
Support for this was added in d5d05cdb3d4 and will be in OpenSSH 8.5:

    > The authenticity of host 'test (10.0.0.1)' can't be
established.
    > ECDSA key fingerprint is
SHA256:milU4MODXm8iJQI18wlsbPG7Yup+34fuNNmV08qDnax.
    > This host key is known by the following other names/addresses:
    >     ~/.ssh/known_hosts:1: host.example.org,10.0.0.1
    >     ~/.ssh/known_hosts:2: [hashed name]
    >     ~/.ssh/known_hosts:3: [hashed name]
    >     ~/.ssh/known_hosts:4: host
    >     ~/.ssh/known_hosts:5: [host]:2222
    > Are you sure you want to continue connecting
(yes/no/[fingerprint])?
