Public bug reported:

When nova-compute restarting, it will  trigger soap requests to vCenter Server.
oslo.vmware set default http pool size to 10. [1] 

This is not satisfy in large scale environment, in nova-compute log, there are lots of warning like: 
WARNING urllib3.connectionpool [-] Connection pool is full, discarding connection

In this situation, users can not set the http pool size, the way we tune connection_pool is modify oslo.vmware code.
We can make it configurable in Nova vCenter driver side.
