error when adding container to pod with network information

Browse Source 
because a pod's network information is dictated by the infra container at creation, a container cannot be created with network attributes.  this has been difficult for users to understand.  we now return an error when a container is being created inside a pod and passes any of the following attributes:

* static IP (v4 and v6)
* static mac
* ports -p (i.e. -p 8080:80)
* exposed ports (i.e. 222-225)
* publish ports from image -P
