    Enable or disable an ESXi firewall rule set.

    host
        The location of the host.

    username
        The username used to login to the host, such as ``root``.

    password
        The password used to login to the host.

    ruleset_enable
        True to enable the ruleset, false to disable.

    ruleset_name
        Name of ruleset to target.

    protocol
        Optionally set to alternate protocol if the host is not using the default
        protocol. Default protocol is ``https``.

    port
        Optionally set to alternate port if the host is not using the default
        port. Default port is ``443``.

    esxi_hosts
        If ``host`` is a vCenter host, then use esxi_hosts to execute this function
        on a list of one or more ESXi machines.

    credstore
        Optionally set to path to the credential store file.

    :return: A standard cmd.run_all dictionary, per host.

    CLI Example:

    .. code-block:: bash

        # Used for ESXi host connection information
        salt '*' vsphere.enable_firewall_ruleset my.esxi.host root bad-password True 'syslog'

        # Used for connecting to a vCenter Server
        salt '*' vsphere.enable_firewall_ruleset my.vcenter.location root bad-password True 'syslog' \
            esxi_hosts='[esxi-1.host.com, esxi-2.host.com]'
    '''
