  - ci/deploy.sh: Do not pass SSH_KEY to Fuel deploy

    OPNFV Jenkins jobs for Fuel and Armband define the variable SSH_KEY,
    which gets passed down to Fuel's ci/deploy.sh, leading to a conflict
    between the original key and the destination key paths, which in
    the default case overlap, leading to a deploy-breaking fault.

    Fuel@OPNFV is not affected by this behavior due to a "sudo" call
    that does not pass down enviroment variables (i.e. without `-E`).
