wic: get rid of listing properties

Functionality of listing and using properties of wic images
does not exist in the wic code. However, there are plenty of
help and usage content about it, which is very confusing.

Removed everything regarding image properties from wic codebase.

     sources listed by the 'list source-plugins' command.  Users can

     details.
-
-    The third form enumerates all the possible values that exist and
-    can be specified in a OE kickstart (wks) file.  The output of this
-    can be used by the third form to print the description and
-    possible values of a specific property.
-
-    The fourth form enumerates all the possible options that exist for
-    the set of properties specified in a given OE kickstart (wks)
-    file.  If the -o option is specified, the list of properties, in
-    addition to being displayed, will be written to the specified file
-    as a JSON object.  In this case, the object will consist of the
-    set of name:value pairs corresponding to the (possibly nested)
-    dictionary of properties defined by the input statements used by
-    the image.  Some example output for the 'list <wks file>' command:
-
-    $ wic list test.ks
-    "part" : {
-        "mountpoint" : "/"
-        "fstype" : "ext3"

-    "bootloader" : {
-        "type" : "efi"
-    }
-    .
-    .
-    .
-
-    Each entry in the output consists of the name of the input element
-    e.g. "part", followed by the properties defined for that
-    element enclosed in braces.  This information should provide
-    sufficient information to create a complete user interface with.
-
-    The final form enumerates all the possible values that exist and
-    can be specified for any given OE kickstart (wks) property.  If
-    the -o option is specified, the list of values for the given
-    property, in addition to being displayed, will be written to the
-    specified file as a JSON object.  In this case, the object will
-    consist of the set of name:value pairs corresponding to the array
-    of property values associated with the property.
-
-    $ wic list property part
-        ["mountpoint", "where the partition should be mounted"]
