Direct users to renewal page on Store instead of /join

/join should only be used when someone can actually buy a new subscription.
/renew should be used when someone already has a subscription that needs
to be renewed.

Since url_for('cloud.xxxx') makes no sense in Pillar, I just hard-coded
/renew instead.
