Description of problem:
Clicking "Load Datacenters" when creating VMWare compute resource complains: "String does not start with the prefix 'encrypted-', so Foreman::Model::Vmware VMWare-vCentre was not decrypted" and you can not save the compute resource. No error message is displayed.

Version-Release number of selected component (if applicable):
Satellite-6.0.3-RHEL-6-20140626.1
VMware-vCenter-Server-Appliance-5.5.0.10000-1624811_OVF10.ova + latest updates

How reproducible:
always

Steps to Reproduce:
1. Start VMware-vCenter-Server
2. Create compute profile with VMWare provider, IP adress set to vCenter server,
user "root" and password "vmware" (credentials I use to connect to "VMware
vCenter Server Appliance" webUI)
3. Click [Load Datacenters]

Actual results:
Nothing happens in webUI besides "Fingerprint" field being populated. Clicking on [Submit] do not save the compute resource

Expected results:
Either error message should appear or [Submit] should save the compute resource
