Configurable:
- Can we obsolete 'rgw relaxed s3 bucket names', and convert it to a new
  option: 'rgw s3 bucket name create strictness'
  Value '0' => existing 'rgw relaxed s3 bucket names = true' logic
  Value '1' => existing 'rgw relaxed s3 bucket names = false' logic
  Value '2' => compliance with AmazonS3 DNS rules

Backwards-Compatibility:
- Make a new option 'rgw s3 bucket name access strictness'
  Same values as above, but used to access buckets, not create new ones.
- Proposed default values:
  rgw s3 bucket name create strictness = 2
  rgw s3 bucket name access strictness = 1

So you can only create DNS-compliant buckets, but still access your
existing non-compliant buckets. Maybe also have keywords of major
releases and 'relaxed' supported in addition to the integer values.

I don't like the names of the config keys, but I'm coming up blank on
something that is shorter while still being immediately clear.
