Add a `project` block to the toml config along with development and CI dependencies and a minimal `build-system` block, doing basically nothing, so that spack can be bootstrapped to a full development environment with: ```shell $ hatch -e dev shell ``` or for a minimal environment without hatch: ```shell $ python3 -m venv venv $ source venv/bin/activate $ python3 -m pip install --upgrade pip $ python3 -m pip install -e '.[dev]' ``` This means we can re-use the requirements list throughout the workflow yaml files and otherwise maintain this list in *one place* rather than several disparate ones. We may be stuck with a couple more temporarily to continue supporting python2.7, but aside from that it's less places to get out of sync and a couple new bootstrap options. Co-authored-by: Adam J.
