Integration with Zenodo

[MartaOB]

Add a new option inside "storage configuration" (ModuleTrain) that has two alternatives to import a Zenodo dataset. The first one has:

• Select field to choose a zenodo dataset
• Select field linked to the previous one to select the dataset's version

The second one has:

• Input field to write a record ID from Zenodo

Both of them use:

• Slide toggle to select if you want to force pull or not

Additional requirements:

• check that if the user has defined zenodo_record_id it has also specified all rclone_* variables, otherwise the task won't launch.
