OK, this GRE crap ain't working. Let's give up! Instead let's
have one tap-capable host per openQA deployment, so all the
tap jobs will go to it. This...should achieve that. Let's see
what blows up.
we have a big mismatch between prod and stg atm (stg has 4
workers, prod has 18). let's make it 14 vs. 8 and also give
stg two worker hosts so we can test multi-worker-host scenarios
NetworkManager entirely ignores the openvswitch devices, the
integration only works with network.service. So turn it on.
Apparently we can have both services enabled and things don't
explode...so far...
This comes from the kraxel.org repo and was added to the infra
repo by nirik. Note that it is technically non-freely licensed.
It contains a FAT implementation; Microsoft has granted an
exemption from the FAT patent purely for the purpose of
implementing a UEFI firmware, so there is a use restriction on
this code. License can be found (as I write this) at:

it seems variables in vars/main.yml are 'role variables' with
a high precedence, while variables in defaults/main.yml are
'role default variables' with a low precedence. This could be
made a hell of a lot clearer in the docs.
This adds openQA server, worker and dispatcher roles, and
applies them to the appropriate hosts. A few secret vars are
required. See trac #4958 for discussion.
