    Allow bootstrapping against clusters and unify host options

    The current settings inside freezer-manage reflect on using host and
    port which are no longer used. In addition, there seems to be no
    splitting of the values in freezer-manage which means that it would
    create a problem when trying to install against a list of hosts as
    the ElasticSearch driver will refuse to accept the list.

    This patch unifies all references of to 'hosts' and changes the option
    to use ListOpt which is comma seperated values in the configuration
    file which are then split into an array by oslo.config, which avoids
    having to split things inside freezer.

    Closes-Bug: #1681931
