In the scope of TCOMP-2058 was introduced a new functionality that allows to add extra dependencies of others connectors to the connector.

Right now the ConnectorReference class is a marker, and I want to deprecate it and use instead annotation ConnectorRef (or smth like that), which will mark the class, and also will mark the fields inside to determine the properties

Why do we need it?
For dataprep connector we don't need family, and name properties, and we may use only mavenReference. But the functionality might be usefull and I want to keep the previous approach. Even so, it doesn't work fully on studio-integration part
