Expose asset id and vm vnc port in asset details

Prior to this commit the asset id value and vm vnc port information was
not exposed in the asset details template. Not having these values
quickly accessible has resulted in a number of user complaints.

We now expose the asset id in the general tab and the vnc port in the vm
tab of assets with corresponding vm records.
