When using protocol version 1, send a finalise message when streaming
is complete so that the zuul_console daemon can delete the temporary
file.
We test this by inspecting the Ansible console output, which logs a
message with the UUID of the streaming job. We dump the temporary
files on the remote side and make sure a console file for that job
isn't present.
