docker_cli_swarm_test: factor out common code

Browse source 
This is repeated 6 times in different tests, with slight
minor variations. Let's factor it out, for clarity.

While at it, simplify the code: instead of more complex
parsing of "docker swarm init|update --autolock" output (1)
and checking if the key is also present in
"docker swarm unlock-key" output (2), get the key
from (2) and check it is present in (1).
