Description of problem:
If the cluster "Default" is deleted or renamed (in my case) the adding of new hosts with the hosted-engine --deploy command will fail in an ideal way.

The output will start like below and continue to spam the last message for 30 minutes until it times out.

[ INFO  ] Engine replied: DB Up!Welcome to Health Status!
[ ERROR ] Cannot automatically add the host to the Default cluster: Entity not found: Cluster: name=Default 
[ INFO  ] Waiting for the host to become operational in the engine. This may take several minutes...
[ INFO  ] Still waiting for VDSM host to become operational...

The host will be added to the HA services, however the engine will not have the host. Adding a new cluster called "Default", the host was added successfully.

I think the hosted-engine should either create a new cluster=Default or simply add it to the first cluster? Alternatively allow the user to input which cluster the host should be added to as to avoid this issue.

Version-Release number of selected component (if applicable):
ovirt-hosted-engine-setup-1.2.0-0.0.master.20140117.gitfaf77a5.el6.noarch
ovirt-hosted-engine-ha-1.1.0-0.0.master.20140118.git3db8f76.el6.noarch

How reproducible:
Always

Steps to Reproduce:
1. Install hosted-engine, rename cluster!=Default
2. Deploy a second host to be added to hosted-engine

Actual results:
setup will hang for 30+ minutes until timeout and the host will be added to the ha-services but not the engine.

Expected results:
host will be added to ha-services and engine.

Additional info:
The other case may be related to Default cluster doesn't have "gluster service" enabled as moving the host to the gluster enabled cluster seems to fail (I think because they are not peers yet).
