vmware_guest relative paths for folder (#26927)

* Re-introduce relative paths to vmware_guest folder:

Move compile_folder_path_for_object function from vmware_guest_find to
utilities
Allow full path or relative path to be specified for the folder
parameter.  We will build the full path to the new VM.

* Remove duplicate check

* PEP8 Fixes
