Common configuration for Language Servers

I found in docs what `ale` currently have several options for configuring specific linters.

However Language Servers also support some common configuration options. Is there an option in `ale` to bypass some config to Language Server?

ex. how it's implemented in `vim-lsp`:
https://github.com/prabirshrestha/vim-lsp/wiki/Servers-Python#workspace-configuration

(i've came to this question while trying to find a way to loose down mccabe warnings in `ale`: https://github.com/palantir/python-language-server/blob/develop/vscode-client/package.json#L73)

Start with ALE's documentation for linter configuration, then compare it with the linked vim-lsp workspace-configuration example and python-language-server's vscode-client/package.json. Done means ALE provides a way to pass common Language Server settings, including the mccabe configuration use case, and documents how to use it.
