Update dependency vmware/govmomi to v0.20.3


misterikkit committed on Oct 4
govmomi is the vSphere client library used by the vSphere cloud provider
and storage plugin. A bug in the SOAP client prevented storage classes
that use vSphere storage policies (aka SPBM) from working.

This bumps our dependency on vmware/govmomi from v0.20.1 to v0.20.3 to
pick up the fix in vmware/govmomi#1498

Here are all changes in the release:
