Subject: [PATCH] Add tax rates to metadata

This doesn't do anything by itself but it lays the foundation for a solid fix for

https://github.com/civicrm/civicrm-core/pull/15895 - ie by having minimum_fee_with_tax as part of our
generally available metadata we get out of all the complexity of doing this in the js layer - which is
what is driving that bug
