run_test_from_archive: Rewritten to be more parallelized.
- Fetch files, create directories and symlinks all simultaneously.
- Opportinistically map the first files arrived instead of processing them in
order.
- Creates all the needed directories in one pass, reducing the number of system
calls like os.path.isdir().
- Add support for 'includes' manifest, e.g. fetch all files from another
manifest in addition to the current one. This permits doing something like:
1. Create a root manifest that contains all the usual script files.
2. Create one manifest per command to run, referencing the root manifest in
the 'includes' section by its hash. Note that includes are recursive.
3. Optionally overide a file in to root manifest from what was defined in an
included manifest.
Add more tests.
