[OE-core] [PATCH 07/10] wic: remove PluginMgr.get_plugin_methods

[Ed Bartosh]

Call methods directly instead of getting them with
get_plugin_methods and then calling.

     This scheme is extensible - adding more hooks is a simple matter
     of adding more plugin methods to SourcePlugin and derived classes.
-    The code that then needs to call the plugin methods uses
-    plugin.get_plugin_methods() to find the method(s) needed by
-    the call; this is done by filling up a dict with keys containing
-    the method names of interest - on success, these will be filled in
-    with the actual methods. Please see the implementation for
-    examples and details.
