Select multiple datasets for compute

[ferrys]

As a user of secure multi party computation, I would like to be able to select multiple datasets at one time so I can compute on them together in my computing environment.

Some notes from a meeting today with @TaniaSchlatter:

The current UI implemented by the cloud class last semester allows a user to select multiple datasets by going to the dataset page and adding the current dataset to a compute batch. We want to change this functionality a little bit, by adding a dropdown at the top of the dataset page which contains something similar to:

In the 4246-compute branch, there is now a 'Compute Batch' dropdown button on the Dataset Page if the dataset is a Swift dataset:

The dropdown options allow users to 'Add to Compute Batch', 'Delete from Compute Batch', 'List Compute Batch' and 'Compute on Compute Batch':

Clicking 'Compute on Compute Batch' sends the user to their desired computing environment with the names of each of the datasets and their container names in the current batch in the url.

Comments from Tania and Mike:

• move the button to the right of Edit
• treat the button as the same button type as "Download" – gray and shaded
• change the button text to "Compute" (drop "Batch") for consistency with the button at the file level
• use render logic to display only one dropdown link for "Add to Batch" vs "Remove from Batch"
• use render logic to display "List Batch" and "Compute on Batch"
• edit the text in the drop down items: "Add to Batch", "Remove from Batch", "List Batch", "Compute on Batch"
• add success/error messages for add/remove actions, use following vague validation message in bundle dataset.compute.computeBatch.success=The list of datasets in your compute batch has been updated.
• clean up code (e.g. remove unused pieces like dataset.compute.link=http://128.31.25.208:3000/ in bundle.properties
