docker driver exposes public methods outside of driver interface - should be private

[Erica Windisch]

The following methods are public and should be prefixed with a _ to indicate that they are private:

     is_daemon_running
     find_container_by_name
     get_available_resource

    Prefix private methods with _ in docker driver

    Private methods should be prefixed with a _ for
    clarity. Although most private methods were
    marked this way, a few were not.

    Renames and marks private:
     is_daemon_running
     find_container_by_name
     get_available_resource
