SSBC: Allow to filter workspaces by ignored and unsupported
Created by: courier-new
Needs design: https://github.com/sourcegraph/sourcegraph/issues/34105
- Implement a new argument on the workspaces query for a
BatchSpecWorkspaceConnection
to allow for filtering ignored and unsupported workspaces (wait on design ticket to decide on argument type) - Add filter button next to "Displaying X of Y" header in workspaces list on both editor and execution screens, which opens a filter menu and allows toggling ignored and unsupported workspaces as visible or not (wait on design for decision about menu options and defaults)
