Implement Uninstall [URL]

[jidanni]

Please make this a clean roundabout trip, leaving the system the way it was

# pip   install https://electrum-ltc.org/download/Electrum-LTC-2.9.3.1.tar.gz
# pip uninstall https://electrum-ltc.org/download/Electrum-LTC-2.9.3.1.tar.gz

or at least have it raise an error.

While I don't think this should start working or raising an error, I think having pip uninstall print a warning when given something that doesn't look like a package name (like a URL or directory path) is a reasonable thing to do.

I've labelled this issue as an "awaiting PR".

This label is essentially for indicating that further discussion related to this issue should be deferred until someone comes around to make a PR. This does not mean that the said PR would be accepted - it has not been determined whether this is a useful change to pip and that decision has been deferred until the PR is made.

Related to PEP 610 which, if it gets accepted, would make this easier since we could do an installed package metadata query as opposed to downloading the archive, generating its metadata, then querying for an existing package matching it.
