We do this for two reasons:
- when popping up a credentials prompt, it looks distracting if the waiting
status keeps spinning while the user is typing the password
- the task that updates the waiting status periodically would keep the program
busy, so integration tests would wait forever for the program to become idle
again
We've been sometimes using lo and sometimes using my slices package, and we need to pick one
for consistency. Lo is more extensive and better maintained so we're going with that.
My slices package was a superset of go's own slices package so in some places I've just used
the official one (the methods were just wrappers anyway).
I've also moved the remaining methods into the utils package.
