Turn off snippets for jedi LSP

[PeterJCLaw]

Environment data

• VS Code version: 1.55.0
• Extension version (available under the Extensions sidebar): 2021.3.680753044
• OS and version: Ubuntu 20.04 LTS
• Python version: 3.7, deadsnakes
• Type of virtual environment used: virtualenv
• Value of the python.languageServer setting: JediLSP

Expected behaviour

class Thing: pass

Th<tab> # should complete to:
Thing|     # cursor after completed word

Actual behaviour

class Thing: pass

Th<tab> # should complete to:
Thing(|)  # cursor between completed parens

As far as I can tell this is specific to the JediLSP integration -- changing my language server to Jedi results in the expected completion.

I can maybe see why this is maybe useful if you're planning to construct an instance or calling a function, though there are many other places where callable symbols are used in which you don't want this to happen -- passing them as callbacks and type annotations for example.

@PeterJCLaw This should be filed on https://github.com/pappasam/jedi-language-server. We don't control this behavior in the extension.

Ah, thanks, I'd assumed that the insertion text and cursor position was controlled by the extension.

@luabud we have snippets on be default in jediLSP. This seems to be caused by that. Should we turn it off. It is off for the other language server. But we don't have a setting to control this behavior. Need your opinion on should we turn this off by default or provide a setting.
