[wrangler] Add preview auto-provisioning for KV and R2

[maxwellpeterson]

wrangler preview can now provision new, per-preview resources for binding-only entries in the previews config block. wrangler preview delete cleans up only those auto-provisioned preview resources and leaves explicitly configured resources untouched. Preview auto-provisioning does not update the previews config block, since resource names and IDs are unique for each preview.

This implementation is incomplete and not intended to be reviewed or merged yet. Auto-provisioning for wrangler preview should support the same set of resources as wrangler deploy. wrangler preview is currently missing a number of resources, including D1 and others.

  • Additional testing not necessary because:
• Public documentation
  • Cloudflare docs PR(s):
  • Documentation not necessary because: wrangler preview is still in private beta
