Add additional schema metadata to the Fields for the SQL Server Connector in order to generate the ConnectorType schema for the Debezium UI.
You can find an example in the PR that has the base work for this task here: https://github.com/debezium/debezium/pull/2558
The main focus is about adding configuration for `public Field required()` for mandatory fields (replace `.withValidation(Field::isRequired)` with `.required()` and `public Field withGroup(GroupEntry group)` calls to assign a proper group for the Field property and best position in that group.
Also validate if all neccessary properties are added to the `CONFIG_DEFINITION`.
Before we can start with it we need to split up changes in the PR of
DBZ-3364 to get the base work prepared.
