Add a small program to iterate over the templates directory and
generate a go map of name to file data. This is so we can compile
these templates into the dex binary instead of requiring files on
disk.
Also add a Makefile rule to do this automatically.
It's not clear that the best way to manage clients is through a
gRPC based command line tool. For example we may explore an admin
dashboard and enable bootstrapping through static clients.
For now use static clients while we hold off on a more concrete
proposal.
