This is tracked via https://projects.linaro.org/browse/LAVA-1201

As you can see from the above card that is the basic idea where we do
not want the lava-master to know what kind of worker is running.

Such an use-case is the idea behind the text explained in "TBD" section
of the above card. In this case we plan to control it via two things:

1. Absence of LXC protocol related content in the job yaml.
2. A setting in lava-dispatcher that governs whether running fastboot
   and adb is allowed directly on this dispatcher. This is required for
   LAVA instances that does not run within virtualized containers and
   hosts more than one DUT.

The above implementation will require changing things like:

* Provide equivalent pipeline actions that does not use an LXC
connection or lxc-attach
* Constructing a different job action pipeline from what will be used
for a normal LXC protocol based job.

Though we started with the above idea, later our design discussions led
to lava-lxc-mocker.

We will re-iterate to see if we can support new jobs that will
completely use direct access without LXC, which will be taken up once we
have lava-lxc-mocker use case done, which is still valid for providing
compatibility for reusing jobs that uses LXC protocol.

Thank You.
