Add support for Debian system

We can add suport for Debian system due to have the
zaqar package in Debian system.
The Debian system does not support the use of services to run
a second instance, because there is no zaqar-server@.service
in zaqar package, so do not test it. I will Re-test it after
the zaqar package solve the problem.
