Could the client detect proxy configuration from the 'environment'?

What I mean is the JVM hosting the client, if executing in a proxied environment will probably be already configured to work with the proxy.

For example by having system properties like https.proxyHost and https.proxyPort set.

Or via something like this:
https://java.com/en/download/help/proxy_setup.xml

Or a number of other ways I might be missing.

In other words the cf java client should strive to pick up proxy configuration automatically in a similar way that the JREs built-in http client libraries do.

issue 中没有指定源文件或测试。请从 Java 客户端的 HTTP 和代理配置入口开始，结合链接的 JRE 代理指南，检查 https.proxyHost 和 https.proxyPort 等 JVM 属性，并为自动代理发现定义测试。完成的标准是受支持的 JVM 代理设置无需手动配置即可生效。
