Create initial monthly billing cronjob
Renews all expired plans where there is enough balance to do so.
Sets expires_at on all renewed plans to one month from today, so even if they
were very expired they are up to date the moment they pay.
Cronjob to check pending BTC transactions
When they become confirmed, insert them into the transactions table.
We can never double-insert because of the PRIMARY KEY on transaction_id, so the
script is always safe to run even if something ends up in redis twice.
Endpoint that pushes all unknown transactions into Redis
The intent is to use `electrum notify <address> <app>/electrum_noify?address=&customer_id=`
The app asks electrum for all transactions on that address, and then checks
which ones we *don't* already have recorded in the transactions table. These
are pushed into Redis to be picked up by a to-be-written job that will write
them to the transactions table after 3 confirmations.
Save bidirectional association for customer_id in redis
Hide loading spinner on error so the error state can show
In production, require customer_id be passed also.
As a security measure, so people can't modify the cards on arbitrary JIDs.
Going to use this as a customer id for the whole billing system
So it's not really braintree specific, even if we make it match the one there.
