Add more ignore and skip tests to the list

[meaksh]

Based on the initial Salt Shaker runs, these are some tests we need to ignore to prevent errors and also skip to avoid hanging executions.

Let me quote the README:

All changes must come via a pull request that is approved by at least two other maintainers. All new entries must include a comment that explains why a given test is failing. The pull request description should explain why a test case is not getting fixed and instead added to this skiplist.

I'm afraid both your commit message and the actual changes don't fulfil these requirements.

I think it would be good to see how hard it is to fix the boto-related tests. I found out that many of them are due to a misalignment between imports in tests and imports in the application. In that case HAS_BOTO is True for the tests but False for the application.

Other than that, I would drop tests we don't plan to fix. If they are unmaintained by us and by upstream, I doubt they will be fixed.

Thanks for the feedback @agraul. I've removed the ones that are not longer needed after the changes we are introducing here: openSUSE/salt#616

Boto tests surprised a bit, but after reading the comments it's clear now :-)
