datacrunch: convert to .default scheme for consistency

Previously, DataCrunch had its .generated files tracked directly in git.
This worked for fresh clones but meant that running 'make cloud-config'
would cause the files to show as modified in git status.

This converts DataCrunch to use the same .default scheme as the other
cloud providers. The .generated files are now gitignored, and .default
files provide the sensible static defaults. The Makefile copies from
.default to .generated if the generated files don't exist.

This makes DataCrunch consistent with Lambda Labs, AWS, Azure, and OCI,
and prevents git pollution after regenerating from the API.
