When connected to an agent, L{SSHUserAuthClient} can use it to
request signatures of particular data with a particular L{Key}.

L{SSHUserAuthClient} looks up public keys from the agent using the
L{SSHAgentClient} class. That L{SSHAgentClient.getPublicKey} returns a
L{Key} object with one of the public keys in the agent. If no more
keys are present, it returns L{None}.

L{SSHUserAuthClient.getPublicKey()} is able to get a public key from
the first file described by its options' C{identitys} list, and return
the corresponding public L{Key} object.

If an agent is present, but doesn't return a key,

If L{keys.Key.fromFile} raises a L{keys.BadKeyError}, the
L{SSHUserAuthClient.getPublicKey} tries again to get a public key by
calling itself recursively.

L{SSHUserAuthClient.getPrivateKey} will load a private key from the
last used file populated by L{SSHUserAuthClient.getPublicKey}, and
return a L{Deferred} which fires with the corresponding private L{Key}.

L{SSHUserAuthClient} can get a private key from a file, and return a
