Reverting TOTP changes from rc branch

[trmartin4]

Type of change

- [ ] Bug fix
- [X] New feature development
- [ ] Tech debt (refactoring, code cleanup, dependency upgrades, etc)
- [ ] Build/deploy pipeline (DevOps)
- [ ] Other

Objective

Reverting 3 commits that implement PM-2128. The initial implementation of this work assumed that we needed to cache all types of 2FA tokens, not just TOTP tokens. Rather than try to patch this for the release, we are reverting it so that we can have a more complete solution in the next release. The changes will stay in master and be iterated upon there in preparation for the November release.
