organize imports action

[0x8f701]

It'll be good to have this feature so that we can remove unused imports

cc #3301

Actually, there are several operations I expect for "organize import" feature:

• Remove all redundant imports, and remove curly brackets if unneeded
• Merge all imports as much as possible, or split all imports, one identifier for one line
• Sort (and maybe insert appropriate blank lines between groups) the imports (the first of which can be already done by cargo fmt)

It would also be nice if local imports could be canonicalized, so that it consistently uses relative or absolute paths (or has a rule for determining which to use).

I would follow the approach intellij uses, with imports grouped by standard library, external, and local, and alphabetized within each group.

I like the suggestions here (merging and sorting), but removal of unused imports is by far the what I'm missing the most.

Is there any ongoing work on this issue?

There is already diagnostic info and quick fix for unused imports, what is stopping this from happening?
