Add pricing_adjustments to integrations API

Adds the optional pricing_adjustments field to CreateIntegrationRequest,
UpdateIntegrationRequest, and IntegrationDetailResponse, plus the new
PricingAdjustments and PricingMultiplier component schemas. The multiplier
keys mirror the pricing keys in the Portkey Models database.
