add convenience tools

The following are some convenience tools that I created during grenade
refactor which might make sense in the tree. These make working on grenade
much easier.

cache_git.sh builds a local git mirror so you can set
GIT_BASE=/opt/git and iterate faster.

run_resource.sh <project> <phase> - lets you run resource test scripts
the way we'll run them in grenade for iterative development.

Both scripts include help with '-h' on their usage.
