Support debezium records in CDC

[CyberROFL]

https://debezium.io/

According to debezium documetation there a currently two possible kinds of records:

• with schema

  {
    "schema": {...},
    "payload": {
      "op": "u",
      "source": {
        ...
      },
      "ts_ms" : "...",
      "before" : {
        "field1" : "oldvalue1",
        "field2" : "oldvalue2"
      },
      "after" : {
        "field1" : "newvalue1",
        "field2" : "newvalue2"
      }
    }
  }

• without schema

  {
    "op": "u",
    "source": {
      ...
    },
    "ts_ms" : "...",
    "before" : {
      "field1" : "oldvalue1",
      "field2" : "oldvalue2"
    },
    "after" : {
      "field1" : "newvalue1",
      "field2" : "newvalue2"
    }
  }

As you can see it looks very similar to the CDC records in the NEW_AND_OLD_IMAGES mode and JSON format.

• Add new CDC format like DEBEZIUM.
• Add schema to the CDC records (in mode with schema).
• Add missing service fields (find out which fields are required and which are not).
• Add (rename) some fields (oldImage — before, newImage — after, etc).
