Use OpenSSH-style public keys as the preferred format of SSH public keys.

Public keys in the old format (raw RFC 4253 blob) are automatically
converted to OpenSSH-style public keys. OpenSSH-style public keys are now
stored in LDAP.

Changed sshpubkeyfp to be an output parameter, as that is what it actually
is.

Allow parameter normalizers to be used on values of any type, not just
unicode, so that public key blobs (which are str) can be normalized to
OpenSSH-style public keys.
