The current grouping of the network e2e tests is a bit messy with old tests residing in too general test files.
These general test files grew with many different tests and at the moment several tests, sometimes doing similar things are distributed between different files, which in turn makes them hard to be found.

It is therefore suggested to reorganize the e2e network tests into a more reasonable grouping.
One such option is as follow: (other suggestions may be proposed as part of this epic)

• network
  • migration
  • bindingcore_masquerade
  • bindingcore_bridge
  • bindingcore_sriov
  • multinetwork
  • dns
