Summary:
Ref T13043. Migrate VCS passwords away from their dedicated table to new the new shared infrastructure.
Future changes will migrate account passwords and remove the old table.
Test Plan:
- Ran migrations.
- Cloned with the same password that was configured before the migrations (worked).
- Cloned with a different, invalid password (failed).
- Changed password.
- Cloned with old password (failed).
- Cloned with new password (worked).
- Deleted password in web UI.
- Cloned with old password (failed).
- Set password to the same password as it currently is set to (worked, no "unique" collision).
- Set password to account password. !!This (incorrectly) works for now until account passwords migrate, since the uniqueness check can't see them yet.!!
- Set password to a new unique password.
- Cloned (worked).
- Revoked the password with `bin/auth revoke`.
- Verified web UI shows "no password set".
- Verified that pull no longer works.
- Verified that I can no longer select the revoked password.
- Verified that accounts do not interact:
- Tried to set account B to account A's password (worked).
- Tried to set account B to a password revoked on account A (worked).
- Spot checked the `password` and `passwordtransaction` tables for saniity.
