Remove SslHttpClient?

I would like to remove this class and all the code (constructors in RemoteDocker, mostly) that makes any assumption regarding securing communication with a remote Docker instance.

My reasoning is that we shouldn't make any assumptions since we will most likely not cover all the possibilities and we are just polluting the library. If the user really needs it and knows what they are doing, they can provide a properly configured HttpClient when instantiating a RemoteDocker.

What do you think?

首先定位 SslHttpClient 和 RemoteDocker 中的构造函数，然后追踪它们如何假设与远程 Docker 实例进行安全通信。在决定范围之前，先查看评论讨论。完成的标准是移除这些假设及相关代码，同时调用方可以提供已配置的 HttpClient。
