Release 30.x: consider restoring the change to not-backfill missing PortBindings #51727
Description
#50874 introduced a change for API > 1.52 that stops the daemon from inserting an empty PortBinding (equivalent to "any host port, all host addresses) when an API request maps a container port to an empty list of host ports.
But, API 1.53 is shipping in v29.2.0 ... it's a breaking change we can reconsider in v30.
At-least the following tests will need fixing:
- TestBridgeINCRouted
- TestDirectRoutingOpenPorts
- TestPortMappingRestore
The following test will need to be updated to test the change:
- TestEmptyPortBindingsBC
