We found out that HttpWaitStrategyTest.testWaitUntilReadyWithTlsAndAllowUnsecure() will fail with java.security.cert.CertificateException: No subject alternative names matching IP address 127.0.0.1 found when used with a Docker daemon that makes containers accessible on 127.0.0.1 rather than on localhost.

This seems to be due to our implementation of allowInsecure in HttpWaitStrategy, where we used a X509TrustManager, that only performs part of the certifacte validation.

This PR changes this implementation to now use a X509ExtendedTrustManager, to ignore this check accordingly. We don't consider this a security issue, since this is for the explicit use case, where a user wants the HttpWaitStrategy to ignore insecure SSL certificates.
