Binary cache cleanup

[mjhenkes]

What would you like?

Today there is no logic implemented to clean up old or unused cypress binaries from the cache. This could use up a large amount of space on a users computer unnecessarily . With the proposed addition of downloadable browser binaries this problem could get worse. The ask is to design and implement a system to remove binaries after a certian amount of time.

Why is it needed?

To reduce hard drive burden on a users computer over time.

Cases to consider, Does a user have multiple versions of cypress across several different repositories
What does the experience look like when the binary has been removed but npm has not re-installed.

Scope: we could scope this change to just the new browser binaries, but we should at least consider it for the cypress binary as well as we're building out a design that accounts for them.

"remove binaries after a certian amount of time"

• I think this should mean: "remove binaries after a certain amount of time after last use of the binary"
