Feature Request: Add support for [--user USER_ID] in uninstall

[bashenk]

When using adb normally, package manager (pm) gives an option to uninstall a particular app for just a particular user id. It would be useful to have that option in this as well.

e.g.
adb shell pm uninstall -k --user 0 com.example.app

Hi, this sounds like a cool feature. As I am open to PRs, do you like to tackle this issue yourself since I think this is not too complex for somebody new to the codebase? I could give you some hints on how to approach this :)
