    Fix problem with bonds configuration

    * Make bond mode and xmit_hash_policy bond_properties processed firstly.
      Due to if it goes after lacp_rate
      than lacp_rate is not set correctly.
    * Change the way to write into file because old way does not rise an
      error if "Operation not permitted".
    * Move type tests into correct place hence enable them.
    * Add wrapper for get/set /sys/class/... properties
    * don't change bond property if no required
    * filter undefined properties
