   * Returns a trust manager that trusts {@code certificates} and none other. HTTPS services whose

This can be used to replace the host platform's built-in trusted certificates with a custom

Warning: Customizing Trusted Certificates is Dangerous!
   *
   * 
Relying on your own trusted certificates limits your server team's ability to update their
   * TLS certificates. By installing a specific set of trusted certificates, you take on additional
   * operational complexity and limit your ability to migrate between certificate authorities. Do
   * not use custom trusted certificates in production without the blessing of your server's TLS
   * administrator.
