[FEATURE]: Add support for S3 global settings

[hrtmhood]

Describe the solution you'd like
Currently the S3 module allows creation of S3 buckets only. Need also to be able to configure the settings within the isi s3 settings global CLI

isi s3 settings global view
         HTTP Port: 9020
        HTTPS Port: 9021
        HTTPS only: Yes

This should also include the S3 zone settings

isi s3 settings zone view
                   Root Path: /ifs
                 Base Domain:
           Object ACL Policy: replace
Bucket Directory Create Mode: 0777
            Use Md5 For Etag: No
        Validate Content Md5: No
