            - Username + SSH-Key
            - Client Certificates
            - SNMPv1 or SNMPv2c protocol
            - S/MIME Certificate

            - Password only

        Arguments:
            name: Name of the new credential
            credential_type: The credential type.
            comment: Comment for the credential
            allow_insecure: Whether to allow insecure use of the credential
            certificate: Certificate for the credential.
                Required for client-certificate and smime credential types.
            key_phrase: Key passphrase for the private key.
                Used for the username+ssh-key credential type.
            private_key: Private key to use for login. Required
                for usk credential type. Also used for the cc credential type.
                The supported key types (dsa, rsa, ecdsa, ...) and formats (PEM,
                PKC#12, OpenSSL, ...) depend on your installed GnuTLS version.
            login: Username for the credential. Required for username+password,

            password: Password for the credential. Used for username+password
                and snmp credential types.
            community: The SNMP community
            auth_algorithm: The SNMP authentication algorithm. Required for snmp
