On jenkins, place all logs and manage docker volumes in the workspace instead
of a /tmp/* dir. Use $WORKSPACE/logs as docker volume base to begin with, thus
there needs to be no copy from /tmp to $WORKSPACE/logs.
On non-jenkins runs, place all in a /tmp/* dir still, but also skip copying of
the logs: just have a /tmp/logs symlink to the last tmpdir.

To remove code dup and prepare a change to where logs are written, add
collect_logs() to jenkins_common.sh and call that from each jenkins.sh after
the tests are done.
The 'rm -rf' is already done before a test starts. No need to do that again
after each test.
