systemd service file should contain Documentation section

[mkudlej]

I think that there should be Documentation section (https://fedoraproject.org/wiki/Packaging:Systemd#Documentation_field) in service file for systemd.

@mkudlej Is it really required?, I dont see it in any other tendrl component (https://github.com/Tendrl/gluster-integration/blob/master/tendrl-gluster-integration.service, https://github.com/Tendrl/api/blob/master/tendrl-api.service,https://github.com/Tendrl/notifier/blob/master/tendrl-notifier.service, https://github.com/Tendrl/node-agent/blob/master/tendrl-node-agent.service)

@rishubhjain I've filed similar issues for other components too.
The idea here is to have at least some documentation for Tendrl daemons because they haven't manpages. I think adding one file with link to README on github for component is OK.

@rishubhjain you can just point to latest install guide below in the service doc
