Missing subscription_id from schema

[huntdm07]

There are two foreign keys in the transactions table for a given merchant account: customer_id and subscription_id.

subscription_id is not currently present in the schema of this tap, but is essential for business logic when reconciling, for example, payment data for multiple subscriptions to a single user, or monthly payments under a single subscription.

A full schema for the transactions table is documented here.

Hey @huntdm07. Sounds like that would be a valuable addition. Can you create a PR to add that to the schema over here? https://github.com/singer-io/tap-braintree/blob/master/tap_braintree/schemas/transactions.json

Hey @briansloane, I took the liberty to do this. I have a PR for this and I tested this and works! Could you apply privileges to me so I can contribute to this repo?
