Enable support for Raspberry Pi

[wombathuffer]

Thanks for refactoring the code - your doing a great job here!

I'm using your role on a pi3, so I have a few modifications, I would ask you to add?

1. Could you please add armv7l: "arm64" to docker_architechture in vars/main.yml ?

2. Could you add the following to the bottom of tasks/setup-docker-compose.yml ?

  when: ansible_userspace_architecture is defined 
- block:
  - name: Pip install Docker Compose.
    pip:
      name: docker-compose
      extra_args: --user
      executable: pip3

  when: ansible_userspace_architecture is undefined

This enables docker compose to be installed via pip on my type device. :)

Thank you!!

I have tried, but either I'm too stupid to do a pull request on your repo, or I lack access.. I'm not that good at gitting...

$ git push origin Raspberry_Pi3_support
Enter passphrase for key '/home/me/.ssh/id_rsa':
ERROR: Permission to atosatto/ansible-dockerswarm.git denied to deploy key
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Hi @wombathuffer, To create a pull request, you need to Fork this repository (which creates your own personal copy of the repository), push your changes to a new branch on your fork and then, on the GitHub page for your repository, create a pull-request (which requests that @atosatto pull the changes from your repository to their repository).
