Method:   POST

Required parameters:

    * label: a string specifying the signer

Optional parameters:

    * certificate: a PEM-encoded certificate of the signer
    * usage: a string array of key usages from the signing profile
    * expiry: the expiry string from the signing profile

Example:

    $ curl -d '{"label": "primary"}' \
          ${CFSSL_HOST}/api/v1/cfssl/sign  \
          | python -m json.tool
