#482) (#483)

This also adds an `is_saved` argument to the pyls_lint hookspec, since
pylint doesn't expose an API for operating on in-memory contents, only
files.

Fixes #129

* vscode: pyls executable path can be configured via "pyls.executable" parameter.

* vscode: fixed identation

`Config.settings()` takes a few milliseconds to run and reads config files from disk. This function runs multiple times during initialization and before every linting request. This means we can very effectively cache the results.

This PR uses `lru_cache` to cache the the result of `Config.settings()`. The cache is invalidated when the config is updated or a config file is changed.

Fixes #305

Fixes #515 
Fixes #526 

Also only generates snippets for positional args

Fixes #520
