VMware: Rewrite get_resource_pool method for correct resource_pool selection (#39792)

* rewrite get_resource_pool method for correct resource_pool selection
* only keep name if path is given for cluster, esxi_hostname or resource_pool
* Revert "only keep name if path is given for cluster, esxi_hostname or resource_pool"
* This reverts commit 50293ec763c024b0eaceac5d775ccc0ad3ff8bd7.
* if the name argument contains a path, only use the last part for matching
* remove path from cluster argument in tests
* remove find_objs in favour of reusing find_obj with an extra folder argument
* fix find_obj ignoring first if name is not given
