PR 1/6

Enhancement

What does this PR do?

Updates the upgrade downloaders to return insufficient disk error
Introduces custom error for insufficient disk space
Insufficient disk errors stops download retries

Why is it important?

The current error is less user friendly and includes unnecessary information
Disk errors get replaced by context deadline error when retries time out, this pr fixes this for disk space errors.

Hey @kaanyalti, I'm having a bit of a hard time reviewing this PR because of the amount of changes in it. I understand most of them are related to testing — making the code more testable and/or adding more test coverage — and that's a good thing. But I do think these changes have made the code more indirect and harder to review.

Would it be possible to break this PR up into multiple PRs, each one only containing a set of related changes? For example, you're introducing a ProgressReporter type in this PR and tests + code related to it. Would it be possible to extract these changes into their own separate PR, then have a follow up PR that builds upon them with another set of related changes, and so on? Ultimately, it would be ideal if there was a final PR in such a series that introduced ErrInsufficientDiskSpace and only any changes strictly related to that.

Yes I can split the PR, will start posting the smaller PRs right away

After having a discussion with @ycombinator I switched my approach to mocking stdlib functions and simplified the tests. This way I was able to remove much of the complexity from before and reduced the amount of changes. I won't be splitting the PR, however I'd still be happy to do so if it'll help reviewers.
