LSIF: Update UI to reflect change from LSIF jobs to uploads
Created by: efritz
Update the UI to reflect changes from https://github.com/sourcegraph/sourcegraph/pull/6875. This PR replaces all LSIF job resources with LSIF upload resources, which are similar but a bit more specific. There is no job type and the arguments are fixed (repo, commit, root, and filename).
Both internal jobs and scheduled jobs are no longer a concept and have been removed from the UI.
This will be merge only after https://github.com/sourcegraph/sourcegraph/pull/6875.
