tests: Use swarm-mode for api tests

* Swarm-mode is the fastest cluster to deploy since it doesn't
  require to pull anything from outside.
* Add the output nodes for swarm-mode too.
* Disable copy logs (I think a better practice is to copy logs
  on demand).
* Don't run test_create_list_sign_delete_clusters, because it is
  very unstable on the CI.

2nd commit message:

Update to Fedora Atomic 26

This patch moves the current master to test against Fedora Atomic 26,
in addition, it switches to downloading from Fedora mirrors.

3rd commit message:

Set default iptables FORWARD policy to ACCEPT

With the release of Docker 1.13 which is available in Fedora
Atomic 26, it no longer sets the policy of the FORWARD chain
to ACCEPT[1].  Therefore, CNI networking such as Flannel will
cease to work.

This patch sets the policy to ACCEPT so that traffic can work
once again for deployments which are based on Docker versions
which are newer than 1.13
