Check that the actor catalog and configured catalog contains valid jsonschema definitions before persisting

[bnchrch]

First noticed

https://github.com/airbytehq/oncall/issues/2703

Problem

We do not validate if the catalog emitted from a connector is valid json schema

As a result a catalog was persisted and used for months until the error was eventually caught by the Catalog Diff Method which throws an exception in this case

Quick Fix

We loosened the check of the catalog diff: airbytehq/airbyte-protocol#44

Long term fix

Use a JsonSchema validator on every stream definition before writing a catalog or configured catalog.
