We need a clone of the aggregator with the submodules updated in order to run the build.

We could clone the aggregator on each build, in the build directory.  Pro, it's a clean repo.  Con, it takes a significant amount of time and disk resources to clone all ~25 repos.

We could use the same aggregator clone for all builds within one stream.  At the start of the build the aggregator can be reset using something like:

git clean -f -d
git reset --hard HEAD
git submodule foreach git clean -f -d
git submodule foreach git reset --hard HEAD

Then the aggregator could be updated and the submodules updated.
