Improve CI (#198)

* Use remote temp path, replace remote lookups.

* Copy local files.

* Change docker resource name prefix from ansible-test to ansible-docker-test to avoid collision with ansible-test's containers.

* Fix typos.

* We don't neceessarily have a TTY.

* Use hopefully less collision-likely subnet.

* More collision avoidance.

* More changes.
