find_pool in vsphere_helper.rb has subtle errors

[glennsarti]

The logic used to traverse the tree uses the object names for traversal, however if two objects have same name e.g. a Folder and a Resource Pool, and are in a particular order find_pool will throw errors.

This is similar to issue #204 .

Perhaps the find_pool code should be using a PropertyCollector to get vCenter to do an inventory search instead.

e.g. http://pubs.vmware.com/vsphere-60/index.jsp?topic=%2Fcom.vmware.wssdk.pg.doc%2FPG_PropertyCollector.7.1.html

Find_pool is no longer used. I will submit a PR to remove this.
