* Installed stripe@7.4.0
refs #38
We were relying on stripe being installed in Ghost, this moves the dep
to the correct package.
* Created exponentialBackoff wrapper for stripe api
refs #38https://stripe.com/docs/testing#rate-limits The stripe docs suggest to
use exponential backoff when recieving a rate limit error. This wrapper
will wrap stripe api calls, and retry them after 1s,2s,4s,8s,16s until
eventually failing. This gives a total of 5 retries over 31s.
* Added wrappers around the stripe api calls
refs #38
* Ensured all calls to stripe api go via exp backoff
refs #38
* Scaffolding out the error handling for stripe api
* Forwarding all errors
* Refactored stripe api into modules

- Sets up common logger structure with custom logger passed through

* Updated payment processer service to keep static ready promise
