The default is 0, which means all hosts. If set to 1, each host would run a playbook all the way through before moving
on the next host. Fact gathering is still parallel, regardless of the serial setting.
to an additional pattern (a subset) specified on the command line. For instance, a playbook could be reusable
and target "webservers" and "dbservers", but you want to test only in the stage environment, or a few boxes at a time.
./group_vars/groupname.yml (for all groups the host is in)
./host_vars/hostname.yml (for the hostname given in the inventory)
This requires an actual inventory file, not script and the paths are relative
to the directory of the inventory file.

Allow groups to be defined on a per-host basis
This makes it possible to define on a per-host basis what groups a host is in.
When managing a large set of systems it makes it easier to ensure each of the
systems is defined in a set of groups (e.g. production/qa/development,
linux/solaris/aix) rather than having to add systems to multiple disconnected
groups.
----
- host: system01
- host: system02
- host: system03
- group: linux
hosts:
- system01
- system02
- group: solaris
hosts:
- system03
- group: production
hosts:
- system01
- system03
- group: qa
- system02
- group: dbserver
hosts:
- system01
- group: ntpserver
hosts:
- system02
- group: webserver
- system03
----
Can be redefined as:
----
- host: system01
groups: [ linux, production, dbserver ]
- host: system02
groups: [ linux, qa, ntpserver ]
- host: system03
groups: [ solaris, production, webserver ]
----
get_hosts() was treating [] (meaning complete restriction, no hosts allowed)
the same as None (meaning no restriction, all hosts allowed). Fixed logic.
