Add a "copy as import" code action

[brettcannon]

PyCharm has something like this, and it's incredibly useful when you want to import a function from your codebase e.g. in a Python REPL.

Let's say you have a file mypackage/foo/bar.py containing a test function. Then this action would copy from mypackage.foo.bar import test.

PyCharm copies mypackage.foo.bar.test but I think an actual import statement is more useful.

@ThiefMaster, is there a description of the behavior or a gif that shows the functionality? thanks!

Note that the way PyCharm copies it is not perfect since it cannot be used as-is in Python code or a REPL (I wrote my own ipython extension for this when I still used PyCharm). But the gif shows pretty well how it works. The format how it's copied could be made configurable (placeholders for the symbol itself and the module path to it), or it could be always a "Copy as import" action resulting in a from ... import ... string as that's probably the most useful.
