Jonas Pfenniger f6d361b2e2 AWS | storage: big refactor
Logics have been centralised:

* region to hostname
* url generation
* signature
* chaning scheme also changes the port

During the process a couple of inconsistencies have also
been fixed.

Known limitations:

When using the @endpoint with a custom port you need to specify the port
when using get_object_http_url or get_object_https_url.

When using bucket names that contain dots outside of us-east-1 make sure to
access it with the same region in your AWS::Storage.

# List information about objects in an S3 bucket

# @param bucket_name [String] name of bucket to list object keys from
# @param options [Hash] config arguments for list. Defaults to {}.
# @option options delimiter [String] causes keys with the same string between the prefix
# value and the first occurence of delimiter to be rolled up
# @option options marker [String] limits object keys to only those that appear
# lexicographically after its value.
# @option options max-keys [Integer] limits number of object keys returned
# @option options prefix [String] limits object keys to those beginning with its value.
#
# @return [Excon::Response] response:
# * body [Hash]:
# * Delimeter [String] - Delimiter specified for query
# * IsTruncated [Boolean] - Whether or not the listing is truncated
# * Marker [String]- Marker specified for query
# * MaxKeys [Integer] - Maximum number of keys specified for query
# * Name [String] - Name of the bucket
# * Prefix [String] - Prefix specified for query
# * CommonPrefixes [Array] - Array of strings for common prefixes
# * Contents [Array]:
# * ETag [String] - Etag of object
# * Key [String] - Name of object
# * LastModified [String] - Timestamp of last modification of object
# * Owner [Hash]:
# * DisplayName [String] - Display name of object owner
# * ID [String] - Id of object owner
# * Size [Integer] - Size of object
# * StorageClass [String] - Storage class of object
