[Improve][SDK] Optimize the ProxyClientConfig class

[gosonzhang]

Description

There are two types of senders, TCP and HTTP, in the DataProxy SDK, but the same ProxyClientConfig class[a] is used. After analysis, several problems exist:

1. The configuration items of TCP and HTTP are different, which are easy to misuse in business use and need to be completely distinguished according to different uses;

2. Some configurations are not named in a standardized way and have been abandoned, or the value settings have no range control and need to be modified;

3. The necessary content printing and comparison functions are missing and need to be supplemented

4. Some functions need to be configurable to facilitate subsequent business use
