This commit adds an optional new stripe based pricing table.
If the user is logged in, the email field will be prepopulated with the users email.
The pricing table can be configured in the stripe dashboard.
Once the discourse_subscriptions_pricing_table setting is filled with the pricing table embed code from the stripe dashboard,
the pricing table will be displayed on /s/subscriptions
For more details see https://stripe.com/docs/payments/checkout/pricing-table

* REFACTOR: Use api to add subscribe link
* FIX: I18n subscribe link
* REFACTOR: Use models to store some data
This enables the plugin to show only subscription information which was
generated on Discourse. Subscription data storage is limited to the
external identifiers Stripe generates so we can interact with the API.
* DEV: Test/linting fixes/rake task
