Setup local ansible user

This would be the user that Ansible would use to run playbooks, etc.

It would be nice to have the user default to the user ansible, but be able to be overridden if need be.

We should probably include:

• IPs/CIDRs that allowed to connect using this ansible user
• user/group creation
• authorized keys (including IP(s) that can use the key(s))
• sshd access (including security access and firewall)
• sudo access

Once this is in place, then Ansible projects could be updated to use it.
