Configuration Data model for Incremental in AirbyteCatalog

[cgardens]

Child of #987

Tell us about the problem you're trying to solve

• Add necessary fields for incremental to the AirbyteCatalog.

Impl

• Separate facts about the data versus configuration applied to the data.
  • e.g. table name is a fact. whether it can be synced as full refresh, incremental, or both is a fact. whether this table is going to be synced as full refresh or incremental is a configuration.
• looks something like this? { streams: [ { …, sync_mode: (incremental or full_refresh), comparable: updated_at } ]
