Linode (#9936)

* Fix: Last Played Media Title in plex would stay even when player was idle/off
     Primary Fix is in the "if self._device" portion.
     code in "if self._session" is a catch all but i'm not 100% if it is needed.

* Fixed lint issues with previous commit

* 1st Pass at refactoring plex refresh
Moved _media** into clearMedia() which is called in _init_ and
at start of refresh.

Removed redunant _media_* = None entries

Grouped TV Show and Music under single if rather than testing
seperately for now.

* Fixed invalid name for _clearMedia()
Removed another media_* = None entry

* Removed print() statements used for debug

* Removed unneeded "if" statement

* Added Base Support for Linode

* Removed unused Attr

* Corrected some Typos

* updated requirements & coveragerc

* added import to prevent var not declared errors in linter

* Fixed Typo

* Added Switch Component for Linode and corrected some errors if data was blank

* Updated api lib to hopefully remove dependancy on enum34

* Fixed Reference error

* fix pylint errors

* Update linode.py

* Update linode.py

* Update linode.py

* Update linode.py
