[cloud] Update VPC configuration for existing lambda (#24368)

If a lambda exists but does not have a VPC configuration,
add the VPC configuration when it's present in the ansible
parameters.

Prior to this change, setting VPC configuration on a lambda
that did not have any VPC configuration would ignore that config.
