Replace db-migrate with sequelize-cli

[drewbo]

This should tighten our dependency list up a bit, move to a more maintained dependency, eliminate the cpu-features logging, and be relatively low lift

Notes

• https://sequelize.org/docs/v6/other-topics/migrations/
• https://db-migrate.readthedocs.io/en/latest/

Acceptance Criteria

• [ ] Migrations rewritten to use sequelize-cli instead of db-migrate
