According to the netty docs, TCP fallback is only enabled when setting a socket channel factory. @mfussenegger Any idea how we could test this?

The DNSServer used in https://github.com/crate/crate/blob/79ff2217dde45d6a748b0f31b36c95a7b252878c/blackbox/test_dns_discovery.py#L47 would support a tcp=True option

@mfussenegger I've partly dropped the second commit, just keeping the test changes. Additionally I've increased the default timeout to 10 as suggested. Please re-check.
