Provide option to install packages released on or before a given date

[ChrisJefferson]

Problem

I have the source of a rust program where I didn't store a cargo.lock. I know a date + compiler version on which "cargo build" worked, but now cargo downloads more up to date minor releases of packages + their dependancies, which don't produce a working executable

Proposed Solution

I'm not sure exactly the best way to fix this, but the ability to somehow say "build using the state of packages on date X" would, I hope, allow me to get the program to build + run. Obviously storing cargo.lock would be better, but it's easy to forget.

Thanks for the feature request! I believe this is a duplicate of #5221, so closing in favor of that.
