Make vim more explicit in the code

[oren0e]

If I want to view someone else's code and I see a line like:

from pyVmomi import vim

I immediately want to check out what is vim. But this in turn, takes me to the section of https://github.com/vmware/pyvmomi/blob/a2d5df0b57d7e359b220493c9c77d1635705ef12/pyVmomi/init.py#L219 where I read lines like "Files can just import the top level namespace and we will figure out what to load and when". That's great, but I don't have the tools to figure this out, so I need to know what this vim exactly is.
