Help users fill in template data while filing issues

Feature request
When I file an issue against the python extension, the issue template includes a number of fields that ask for settings values, extension version, OS, etc. Filling these in is time consuming and makes me not want to report issues.

Suggestions

• Add a command that copies the relevant template information to the clipboard

• For the python extension, use VS Code's report issue UI but fill in the template for users automatically. VS Code's JS/TS support for example uses the workbench.action.openIssueReporter command but passes a bunch of information in to pre-populate the issue reporter: https://github.com/microsoft/vscode/blob/3cb12a21b5711022d304d8ea1252bbf620d6eb15/extensions/typescript-language-features/src/typescriptServiceClient.ts#L583

Let the VS Code team know if you have any other ideas on making it easier to report extension issues as well
