Add bucket config to wrangler.toml

[ashleymichal]

adding bucket to a kv namespace entry to allow Wrangler to orchestrate sync of a directory full of assets. Bucket should be a relative path from the location of the wrangler.toml to a directory including assets to be uploaded to KV.

Should there be a default set of directories that get used if no project.assets is specified? We could include some commonly used static-file directories, i.e. public dist build, so any files in these directories would automatically get uploaded if present. This would get us closer to zero-config deployment for many frameworks.

@1000hz i feel like this would be very presumptuous in the context of the current design given that static sites are not the primary use case; however if we instead added a flag to wrangler publish to indicate that the users' intent is to deploy a static site, this would be a good feature.

current status of this feature is a little up in the air; the design at the moment is to nest "bucket" under a kv-namespaces entry. it is possible that this design will change in the next week.

this baseline feature is complete as of #473 . opening new issue for static config.
