Create test addition circuit

[akoshelev]

This change adds a new simple test circuit and integration tests for it. This circuit does not do anything sophisticated and the need for it is dictated by #1141 where I need to test that inputs of size > 2Gb can be handled by our MPC helpers.

I tried to use test-multiply but it just takes too long to process inputs of this size. I estimated ~300M field value pairs need to be submitted to exceed $2^{31}-1$ input size and that makes that circuit to run for 8+ mins.

This circuit is much faster for two reasons. First, it does not require communication. Second, it generates input and shares it using iterators. That makes a big difference - my experiments showed that it takes roughly 9 mins to get test-multiply inputs delivered and ~50 seconds for test-add. It can be further optimized because we collect everything. in .share, but this implementation is good enough for me.

My goal is to use this circuit in a integration test that we run only in CI and that checks inputs greater than $2^31-1$ can be sent via our report_collector client
