Auto merge of #2411 - sbeckeriv:cargo-cache-doc-update-1609, r=alexcrichton

Per https://github.com/rust-lang/cargo/issues/1609 "clarify how the cache works"

Added in a single line that states that the cached packages are only
removed by running the clean command.

Please let me know if this is the wrong spot, incorrect information or just silly.
Thanks
