Add option to prevent full refreshes every month about killbill-analytics-plugin HOT 1 OPEN

A real incremental import is quite difficult because of the data denormalization across tables. We can be smarter however to do less work on a per event basis.

Proposed changes follow (new indices needed).

BUNDLE_* and SUBSCRIPTION_* events

• Refresh only the rows for the bundle associated with the event.
• Care must be taken however to update bundle_account_rank in analytics_bundles.

PAYMENT_SUCCESS and PAYMENT_FAILED events

• Refresh invoice row and invoice item rows for the invoice id associated with the event only (if the payment points to an invoice payment).
• Refresh only the payment tables for the paymentId from the event.

INVOICE_CREATION and INVOICE_ADJUSTMENT events

• Don't refresh payments.
• If the event is INVOICE_CREATION and if the invoice doesn't contain any CBA item, only refresh invoice and invoice item rows for that invoice id. Otherwise, we need to still refresh all invoice and invoice items (impact of CBA across invoices). See killbill/killbill#1143.
