Optimize CLI client dependency loading

Browse Source 
The CLI client was quite heavy in loading in a lot of libraries and
modules during runtime, which slowed it down quite a bit, especially on
slower systems.

This commit makes several major changes to help improve the situation.

1. Don't use pkg_resources to get our version, just hardcode it.

2. Reimplement our entire API call to use a custom http.client-based
system that prevents importing any unnecessary libraries (with a
custom User-Agent too).

3. Implement a lazy-loading method for some of the heavier modules, so
that they are only loaded if absolutely necessary.
