Implement Data Preview related to tasks executed in remote servers

[vascoalramos]

When executing a task, in the history section, we have the possibility to check for that execution Logs, Metrics e Data Previews. However, previewing data is only available when performing a local execution (when performing remote server execution it's not available).

Expected Behaviour

Data previews should be accessible, despite the type of execution.

Current Behaviour

Data previews are only available when performing local executions of tasks,

Possible Solution

As in the case of local execution, it's necessary to implement a mechanism of processing and store the data results of each remote executed task.

Possible Implementation

See implementation of local execution in file TransExecutor.java methods: capturePreviewData and writeDataRow.
