Configuration option to set MSPLS executable path

[michael-ball]

I run a musl-based system, so the version of MSPLS that coc-python automatically downloads won't run for me. Would it be possible to add a configuration option for providing a path to a MSPLS executable? That way I can use the version of the language server I've built for my system.

This would also be extremely helpful to people like me who need wrapper scripts around pyls for picking up dependencies that their build system puts in non-standard places.
