[WIP][Flyteadmin] Add variablemap in dataproxy for dataclass/pydantic

[mao3267]

Current Problem

There are two main components to manage when retrieving the variable_map in the Dataproxy's GetData function: GetDataFromNodeExecution and GetDataFromTaskExecution. Since the variable_map resides in the TaskClosure, it is logical to retrieve it from the Task Repository using the Task's identification details (ID, project, domain, and version).

However, I am unable to determine how to access the output from node execution. Is there a way to retrieve the TaskClosure (or Task) directly from the NodeExecution?

Tracking issue

#6081

Why are the changes needed?

While the task input/output is represented as a dataclass or Pydantic model, using the get function to fetch the FlyteRemote execution output will fail due to the absence of the variable_map information. To address this issue, we aim to provide the input/output variable_map through the Dataproxy as a solution.

What changes were proposed in this pull request?

1. Provide variable_map information in GetData from dataproxy service.
2. Unit tests will be added later.
