Create systemd setup for backend

If anyone wants to create a system service to run teos as a system service to start on the background, the instructions to create it are described in a new section in the install.md file.

Is bitcoind.service installed by default with bitcoin core? If not I think you should publish it too (or put a hyperlink to it).

Agreed, if this depends on another service it would be nice to have a link to it from a well know guide (such as raspibolt)

I added the link to a guide that is quite detailed and updated instructions. This guide has just been released and is quite good in and installation oriented on how to set up on most hardware platforms because it only uses standard Debian Linux commands, as the guide indicates.
