None of the jobs in skylab are running with SSP at the moment.
The problem is twofold,
- skylab_swarming_worker isn't running lucifer with --require-ssp
- We need to push the check for SSP disabled via control file inside autoserv. Currently, job_reporter does this check via https://cs.corp.google.com/chromeos_public/src/third_party/autotest/files/venv/lucifer/jobx.py?l=80 but we don't want skylab_swarming_worker / lucifer parsing the control file at all.

Skylab can't yet run with SSP for a different reason: autoserv only looks on the local disc for control file to execute. 
https://cs.corp.google.com/chromeos_public/src/third_party/autotest/files/server/autoserv?l=327

autoserv needs to be taught to load control file from a devserver when running tests with SSP (and when a control file is provided as the argument)

Basic SSP support in:

https://chromium-review.googlesource.com/c/chromiumos/third_party/autotest/+/1172069/

Still need to make skylab respect control file directives to skip SSP.
That requires pushing the check into autoserv from job_reporter.

Last CL to respect REQUIRE_SSP directive in control files: https://chromium-review.googlesource.com/c/chromiumos/third_party/autotest/+/1173137

autotest: Stage control file inside SSP container for skylab

In skylab, control file name is passed in and autoserv finds the control
file to execute using the name.

When running a test with SSP, autoserv re-executes inside the container
with somewhat modified commandline. For skylab, autoserv now passes in
--control-file unchanged into the container. autoserv execution inside
the container finds and stages the control file. Because the autotest
checkout inside the container is from the test artifacts for the target
build, this results in the control file being staged from the right
build.

TEST=Manual.

dummy_PassServer.ssp is now green in staging: https://chromium-swarm-dev.appspot.com/task?id=3f5c4a793f283010

Currenly, dummy_PassServer.nossp does not properly test that the test is indeed running outside of the container. Nor is it a part of the staging test suite.
I'll update the test / suite such that it will start failing on staging.

autotest: Fail a test when staging SSP artifacts fails

autoserv would continue a test without SSP even when --require-ssp is
set if SSP setup failed. This is bad behaviour because users expect the
test to have used SSP. Instead, fail the test.

autoserv: Infer require_ssp from control file passed to autoserv

Unlike Autotest, Skylab does not pass in a control file to execute by
autoserv, nor does Skylab parse the control file to obtain the options
specified within control files.

Instead, Skylab passes in the name of the control file to execute and
autoserv must infer and respect the options set by a test via its
control file.

This CL makes autoserv respect the REQUIRE_SSP directive in the control
file, if the control file was passed in via --control-name
