> I noticed that tests for dtest in upgrade_tests/thrift_upgrade_test.py are
> flaky.
> The reason this flakiness happens is that we are stopping and starting a node
> too fast without waiting for its full initialisation and then next attempt to
> connect to rpc port fails and whole test fails.
> The fix is rather easy, we just need to wait until it is full started.
