    Adds keypair type in nova-api

    X509 certificates are used by Windows for passwordless
    authentication (WinRM) in a way which can be considered
    consistent with the usage of SSH keys on Linux, as both
    are based on public / private keypairs.

    Enables nova-api to return the keypair type, updates
    nova-api version to reflect the changes and updates the
    unit and functional tests to validate the API changes.

    Unit tests have been updated to ensure that the keypair
    type is not being returned on previous API versions.

    Note: x509 keypair implementation is added in the next
    commit.
