add test to verify vsphere cloud provider report node hostname

**What this PR does / why we need it**:
as in pull #67922 has modify vsphere cloud provider to report
node hostname, this patch is to add the test for it.

also fix an issue at InstanceID(), it suppose to return
cloudprovider.InstanceNotFound when vm not found,  
but it did double error type translation with a retry() logic,  
after removing the retry() (which is not necessary), the logic is simpler, and easier to understand how double translation happened, after the fix,
test TestInstance() can pass
