For bastions using JIT MFA, where MFA can be requested when
attempting to connect through specific groups, or when using
some commands, with respect to MFA being enforced at connection
time directly through the sshd authentication process, one can
now request MFA validation in advance, to workaround problems
in commands such as ``clush`` or ``batch``, and interactive mode.
As tests are now split by modules, the section is autodetected
and taken as the module name, hence a test now only needs a name,
instead of a section & a name.
The chain of executions is as is:
- `docker_build_and_run_tests_all.sh`
- launches several instances of `docker_build_and_run_tests.sh`
- builds docker images with the `target_role.sh` and `tester_role.sh` entrypoints
- inside the tester docker, `tester_role.sh` launches `launch_tests_on_instance.sh`
- the target docker gets tested after setting up accounts, SSH etc.
Previously, these scripts passed options to each other either by a mix of environment
variables and command-line arguments, with some inconsistencies here and there.
Now, `launch_tests_on_instance.sh` supports a lot of command-line options, which can
be specified directly if testing a remote server, or can be passed-through by the calling
script in case of docker tests. `docker_build_and_run_tests.sh` and
`docker_build_and_run_tests_all.sh` also support to passthrough these options down.
