[Feature] Support GET Bucket requestPayment

[ikr0m]

I faced this issue when I tried to create bucket from ansible. This is provision.yml ansible playbook.

---
- hosts: remote_server
  gather_facts: false
  become: yes
  environment: "{{ env_params }}"
  vars_files:
    - vars/main.yml
  tasks:
    - s3_bucket:
        name: s3backup
        s3_url: http://s3.amazonaws.com:4567

It created bucket but resulted Bucket request payment failed to apply in the expected time error. I saw multiple requests like this in fakes3 console:
