vCenter : QueryPerf metrics support

[dbhat-arkin]

Summary:
Our application (vRNI) collects the Host, Datastore, VM metrics using the vCenter SDK : . But, the GoVcSim instance is not returning the required metrics for Hosts, VMs and Datastore. Request to implement the required methods to export the metrics respective to entities in GoVcSim.

Describe the solution you'd like
A clear and concise description of what you want to happen.

Describe alternatives you've considered
Earlier vcsim (simulator of which support ended in vSphere 5.5) had support for exporting the VM metrics.

Additional details:
We had enabled the tracelog for the GoVcSim instance. Below are trace log entries:
