unable to install only clients package without daemon and qemu stuff

[vtolstov]

I need only libvirt lib and virsh binary, with current formula i can't do that by providing
qemu_pkg: ~
extra_pkgs: ~

[baby-gnu]

I'm now ready to split components into sub-directories.

It seems that we have:

• the libvirt server
• the libvirt client
• the qemu for the server (since libvirt server could manage other things)
• the tools could be used independently of server/client (qemu-img, libguestfs)

Here is the directory hierarchy I'm planing to define:

libvirt/
├── client
│   ├── clean.sls
│   ├── config
│   │   ├── clean.sls
│   │   ├── file.sls
│   │   └── init.sls
│   ├── files
│   │   └── default
│   ├── init.sls
│   ├── package
│   │   ├── clean.sls
│   │   ├── init.sls
│   │   └── install.sls
│   └── tls
│       ├── cert.sls
│       ├── clean.sls
│       └── init.sls

└── tools
    ├── clean.sls
    ├── config
    │   ├── clean.sls
    │   ├── file.sls
    │   └── init.sls
    ├── files

    └── package

This way:

• state.apply libvirt will install and configure everything
• state.apply libvirt.server will only manage the server part
• state.apply libvirt.client will only manage the client part
• state.apply libvirt.tools.clean will only unconfigure/remove the tools

This the sub-component scheme as describe in https://github.com/saltstack-formulas/template-formula/blob/develop/docs/TOFS_pattern.rst#using-sub-directories-for-components

Does someone have any comment? (@myii, @Aboe, @vtolstov)

I'm now ready to split components into sub-directories.

It seems that we have:

  libguestfs)

Actually, this is the extra_pkgs. I will provide an extra directory instead of a tools.

@baby-gnu Sounds like an excellent plan to me, always nice to see all of our template-formula structures being applied.
