problem on running shepherd by unpriviledged user

[Reza Alizadeh Majd]

Hi Guix, 

I'm running a series of services by shepherd in user space after user login.
the problem is that this shepherd instance keeps running after user logout.

one other problem is that the communication socket of this shepherd instance 
which was created during login in `$XDG_RUNTIME_DIR/shepherd` destroys during 
logout and I can't access to this instance using `herd`. 

is there any way that I force shepherd to quit on user logout, or alternatively
keep the keep the `$XDG_RUNTIME_DIR/shepherd/socket` after logout to allow 
`herd` to communicate with this instance after re-login?
