Summary0005737: twister should support chaos setting
DescriptionThis chaos setting (maybe specified in the config file) should allow to configure a chaos_probability between 0% and 100%.

For every request, with probability chaos_probability we do not send the actual response back, but instead a plain "service unavailable" response.
TagsNo tags attached.

You mean literally a "503 Service Unavailable" with empty/garbage response body?

The chaos mode should NOT be used on 'demo' deployments; only 'test'.

The chaos option was added here: bcb0c70..f66eb72. There is also a shell script "" under test/ that tells the user how many rounds it needed to hit a 5% "chaos" probability.

0095cd3 adds the unix domain socket serving facility (prepping for 'test' deployment).

NOTE: removing the ".sock" file needs to be done!

Actually, none of the other services remove the ".sock" file, so we'll keep things simple and not do for Twister neither.

The chaos option is implemented (see notes above). Deployment on Gv is in progress.
