introduce Clear Linux OS to the __sysctl type

Note: I choose to use the Slackware code block to not create a new
logical path (and it does work).

+cdist-type__package_swupd(7)
+============================
+
+NAME
+----
+cdist-type__package_swupd - Manage packages with swupd
+
+
+DESCRIPTION
+-----------
+swupd (software update program) is the package manager used on Clear Linux OS to
+manage packages. The package will be installed without optional
+packages. If such packages are required, install them
+separately or use the parameter ``--install-optional``.
+
+
+REQUIRED PARAMETERS
+-------------------
+None
+
+
+OPTIONAL PARAMETERS
+-------------------
+name
+    If supplied, use the name and not the object id as the package name.
+
+state
+    Either "present" or "absent", defaults to "present"
+
+
+BOOLEAN PARAMETERS
+------------------
+install-optional
+    If the package will be installed, it also installs optional packages
+    with it. It will not install optional packages if the original package
+    is already installed.
+
+
+EXAMPLES
+--------
+
+.. code-block:: sh
+
+    # Ensure zsh in installed
+    __package_swupd zsh --state present
+
+    # Remove package
+    __package_swupd zsh --state absent
