Revert "Ship the Credential Management API by default" from M50.
This reverts commit 062c94e083bb1a2ec9df0222cdbdff6b364cb466, which should
have landed only after the M50 branch point.
> Ship the Credential Management API by default
>
> This patch enables the Credential Management API by default.
>
> It also converts the existing CLI flag into a `base::Feature`, which will allow
> us to hook it up to Finch as a kill-switch in case it asplodes the internets.
> This feature flag can be removed after ~a release, once we're confident that
> we're not breaking things.
