Add interop test with unreliable connection

Adds a requirement for GNUTLS_NEXT (3.5.3 or above, in practice we should
install 3.6.3) on the CI.

See internal ref IOTSSL-2401 for analysis of the bugs and their impact on the
tests.

## Interop test with OpenSSL might triger a bug in recent versions (that
## probably won't be fixed before 1.1.1X), so we use an old version that
## doesn't have this bug, but unfortunately it doesn't have support for DTLS
## 1.2 either, so the DTLS 1.2 tests are commented for now.
## Bug report: https://github.com/openssl/openssl/issues/6902
## They should be re-enabled (and the DTLS 1.0 switched back to a non-legacy
## version of OpenSSL once a fixed version of OpenSSL is available)
