/**
 * <b>Note:</b> This is a modified version of {@link io.netty.handler.ssl.util.InsecureTrustManagerFactory} from Netty
 * 4.0.36. Unlike the netty version, this class returns an {@link X509ExtendedTrustManager} instead of an
 * {@link javax.net.ssl.X509TrustManager} instance, which allows us to bypass additional certificate validations.
 * <p>
 * An insecure {@link TrustManagerFactory} that trusts all X.509 certificates without any verification.
 * <p>
 * <strong>NOTE:</strong>
 * Never use this {@link TrustManagerFactory} in production.
 * It is purely for testing purposes, and thus it is very insecure.
