Solution for `git clone` using Ansible for repos with private submodules with github deploy keys

ansible_gitclone_issue_fix

# Problem:
#
# If you use git submodules linking two private github repos, you'll need to create a separate deploy key for each.
# Multiple keys are not supported by Ansible, nor does ansible (when running git module) resort to your `.ssh/config` file.
# This means your ansible playbook will hang in this case.
#
# You can however use the ansible git module to checkout your repo in multiple steps, like this:
#
- hosts: webserver
  vars:
    - destination: /your/dest/path
  tasks:
    - name: App | Cloning repos + submodules
      git: repo=git@github.com:Organisation/{{ item.repo }}.git
           dest={{ item.dest }}
           accept_hostkey=yes
           force=yes
           recursive=no
           key_file=/home/user/.ssh/id_rsa.github-{{ item.repo }}
      with_items:
        -
          dest: "{{ destination }}"
          repo: PrimaryRepo
        -
          dest: "{{ destination }}/app/core"
          repo: SubmoduleRepo

#
# The key part is that `recursive` is set to `no`.
