    @fhueske I preffer a better API with nesting. We can extend `ProjectableTableSource` with
a method like this
    ```scala
    def projectNestedFields(fields: Array[String]): ProjectableTableSource[T]
    ```
    with default realisation.
    override the method in HBase table source and while pushing projection down extract `fieldAccessor`s
from `inputRex` and push them into as well.
    Or create another `ProjectableNestedFieldsTableSource` with the same method.

> Add a {{HBaseTableSource}} to read data from a HBase table. The {{HBaseTableSource}}
should implement the {{ProjectableTableSource}} (FLINK-3848) and {{FilterableTableSource}}
(FLINK-3849) interfaces.
> The implementation can be based on Flink's {{TableInputFormat}}.
