Bucket Operations
===================
PUT Bucket
----------
Creates a new bucket. To create a bucket, you must have a user ID and a valid AWS Access Key ID to authenticate requests. You may not
create buckets as an anonymous user.
Constraints
~~~~~~~~~~~
In general, bucket names should follow domain name constraints.
- Bucket names must be unique.
- Bucket names cannot be formatted as IP address.
- Bucket names can be between 3 and 63 characters long.
- Bucket names must not contain uppercase characters or underscores.
- Bucket names must start with a lowercase letter or number.
- Bucket names must be a series of one or more labels. Adjacent labels are separated by a single period (.). Bucket names can contain lowercase letters, numbers, and hyphens. Each label must start and end with a lowercase letter or a number.
.. note:: The above constraints are relaxed if the option 'rgw_relaxed_s3_bucket_names' is set to true except that the bucket names must still be unique, cannot be formatted as IP address and can contain letters, numbers, periods, dashes and underscores for up to 255 characters long.
Syntax
