endless loop of test container execution

[shayts7]

For test container that register to any docker event - the problem is that execution of test container by tugbot-run trigger events and those events cause tugbot to execute another test container and so on.

Here is debug logs from tugbot:

tugbot has a mechanism to filter out events that were come due to execution of test containers by tugbot itself, but some events were missed (for instance: "network disconnected"), we need to find a way to ignore all events triggered due to test container execution by tugbot.

The missed events are "network disconnect" and "network connect", but I any test container can trigger more type of events (depends on the container implementation).
"network disconnect" and "network connect" contains the container id, so we can check if that container is not "ours" - we need to see how we can do it without bringing performance penalty + after the fix we should add an integration test to check that.
