Display Terraform action errors to user

What does this MR do?

The current terraform table includes action buttons to lock/remove a state. These actions do not display any error information if the mutation fails.

Per our new design, error messages will need to appear inside the table.

We also have an upcoming issue, to add loading styles: #292713 (closed). It is likely the loading styles will also need to appear across the table row.

This MR will:

• Move the Terraform State List to Vuex so custom loading and error fields can be added to each individual state
• Move prop fields to Vuex
• Add #row-details="row" template to the terraform table. This will display new error messages
• Update tests and translations
