Allows setting the current target to any of the groups sorted by target
type (i.e. 'what' type of machine it is). For example, we currently
target our system to a 'workstation' type machine. But we could switch
it to a headless machine which would not install any of the DE/GUI
grouped packages.
If assigning a list of 'host's to a group those become actual hosts and
have their own host variables. What we want to use groups with
child/parent relationships to group things is to not directly use hosts.
This should allow just having a general 'target' system for ansible
which will take all the modifications - but not care whether we connect
to it locally (i.e. running from void) or through chroot.
We can set the connection method for the specific system(s) in whatever
we group as part of the target group then. For local installation we
simply add locally connected hosts and for chroot set up chrooted hosts.
