Addition of New YAML Template

[dev-vaayen]

I have created a YAML Template for Ansible-CMDB that helps with displaying the retrieved Ansible-Facts in the human-readable format of YAML.

In order to use this template, users can run ansible-cmdb -t yaml out/, where yaml is the name of this template and out/ is the directory where Ansible-Facts are being stored.

An excerpt of the output that is displayed after running this command is as follows:

192.168.xxx.xxx:
  ansible_facts:
    ansible_all_ipv4_addresses:
    - 192.168.xxx.xxx
    - 172.xxx.xxx.xxx
    - 192.xxx.xxx.xxx
    ansible_all_ipv6_addresses:
    - fe80::9ab7:9338:xxxx:xxxx
    ansible_apparmor:
      status: enabled
    ansible_architecture: x86_64
    ansible_bios_date: 04/01/
[output.txt](https://github.com/fboender/ansible-cmdb/files/14228415/output.txt)
2014
    ansible_bios_vendor: SeaBIOS
    ansible_bios_version: 1.16.0-debian-1.16.0-5
    ansible_board_asset_tag: NA

The resources used as references for creating this template were as follows:

• Ansible-CMDB json.tpl Template
• StackOverflow post on "How to keep yaml Format when using yaml.SafeDumper"
• PythonLand Guide for "Writing Or Dumping YAML To A File

Please feel free to provide any suggestions or feedback on how this template can be further improved.
