[EPIC] May 19th 2021 repo changes

[bryceml]

This is a tentative list for keeping track of everything happening to the Salt Project repos in May 19th 2021

• https://repo.saltproject.io/opensuse/ is moving to https://archive.repo.saltproject.io/opensuse/, instructions will be updated to show how to use opensuse's packages provided by them.
• repo rpms (i.e. https://archive.repo.saltproject.io/py3/redhat/*.rpm, https://archive.repo.saltproject.io/yum/amazon/*.rpm, etc.) are being deleted. They contain the wrong url anyway, are confusing, and .repo files have been provided instead. Repo rpms on https://repo.saltproject.io will remain for as long as they have a valid url in them, no new ones will be provided, including for 3003.
• Remove redhat symlinks i.e. 7.1, 7.2, etc. for $releasever compatibility.
• Remove amazon linux 1 version symlinks
• Redirect http to https on repo.saltproject.io, archive.repo.saltproject.io
• Redirect repo.saltstack.com to repo.saltproject.io, archive.repo.saltstack.com to archive.repo.saltproject.io, bootstrap, winbootstrap , etc. the s3 prefixed domain names will not redirect so we don't mess up any s3 syncing.

Linking #59378 - from that issue is a May 2021 task:

• We should delete the repo rpms from archive.repo.saltproject.io so they are not confusing. Most people I've talked to say deleting them would be a good thing.
