A testcase each for
- declarative ipv6-only container
Seems odd to define the container IPs with their prefix length attached.
There should be a better way…
- declarative bridged container
Also fix the ping test by waiting for the container to start
When the ping was executed, the container might not have finished starting. Or
the host-side of the container wasn't finished with config. Waiting for
2 seconds in between fixes this.
