[Feature Request] Add customization to allow user to choose PC part.

[brianrudolf]

It seems that this functionality can be added with minimal changes. It would be a good addition if the user could add one or more command line arguments such as:
--component = 3080
or
--component = RTX3080

I'm not sure if the parts would need to be on an internal list to match syntax properly. If the URL needs "RTX 3080" vs "RTX_3080", the user won't know and likely won't care to know.

The argparse library would be a very good option to implement the command line use for the user.

Thoughts on the use of this feature @wandersonca @ChiffX ? I can start the work on this over the next few days.

Yes, that would work. I've also seen people use docopt. You write out the help in a special way and the parser is generated. I don't have a lot of experience with either.

That or we continue using environment variables, it lends itself well to Docker. docker run -e component=3080 followed with a os.getenv("component").

Regarding the components, you can maintain a manifest in YAML like so. This way it's easily updatable.

Interesting, I haven't heard of docopt before but I do have experience with argparse. I am a fan of Docker so I would support a design that allows easy use of it.

I have also wanted to move the search addresses into some form of constants file, I like the look of that YAML file.
