Consider supporting multiple sources for a Resource #1104
Description
Hmm that said we should probably also have nicer support for multiple URLs in included Ignition, so that one could upload configs to multiple S3 regions and have fallback; something like:
'{"ignition":{"config":{"replace":{"source0":"https://s3-us-east-1/mybucket/myconfig.ign", "source1": "https://s3-us-west-1/mybucket/myconfig.ign", "verification": "sha512here"}},"version":"3.1.0"}}'
(Multiple urls should probably require Verification to ensure they are the same and avoid nondeterminism)

Edit: per #1104 (comment), that would be:
'{"ignition":{"config":{"replace":{"sources":["https://s3-us-east-1/mybucket/myconfig.ign", "https://s3-us-west-1/mybucket/myconfig.ign"], "verification": "sha512here"}},"version":"3.1.0"}}'
