Added detection for ZTE zxdsl devices (#10344)

* add yaml files

* Added include/definition/zxdsl.yaml (ZTE ZXDSL Support)
Added include/polling/os/zxdsl.inc.php (Set Hardware)

* Changed includes/definitions/zxdsl.yaml type from "dslam" to "network"
Changed includes/polling/os/zxdsl.inc.php removed unnecessary code
Added Testfiles

* Fixed coding guideline errors (missing spaces)

* Removed unnecessary "use"

* Improved model number discovery
Removed unavailable top graphs
Added System temperature

* Changed Temperature limits according to ZTE datasheet

* Updated Tests
