The ubuntu/debian networking file parsing function
really is more generic than just a rhel utility function
and can be used by others that want to use this functionality
for there own purposes (say in writing down a freebsd network
format instead) so moving this to its own module to encourage
its usage outside of rhel.

Per discussion with Robert @ SUSE since he can't sign the CCA.

So that they can be used by other handlers.

This patch fixes issues in Fedora 18 (and upcoming RHEL 7) which are
present due to their use of systemd:
- store locale configuration in /etc/locale.conf
- store hostname in /etc/hostname
- use a symlink for /etc/localtime (prior code would set the timezone
but corrupt data in /usr/share/zoneinfo due to presence of symlink)
It also contains fixes for issues unrelated to systemd adoption:
- explicitly scan /dev/sr0 with blkid in order to get the optical drive
in the blkid cache. This prevents an issue on systems running 2.6
kernels (such as RHEL 6) in which config disks on some devices won't
be detected unless the device has previously been queried.
(For reference, see https://patchwork.kernel.org/patch/1770241/)
- append a newline when rewriting sysconfig files, as this is customary
text configuration file formatting and is expected by some parsers
(such as the ifcfg-rh plugin for NetworkManager)

This change adds the ability to provide specific package versions to
Distro.install_packages and subsequently Distro.package_command. In order
to effectively use Distro.install_packages, one is now able to pass a
variety of formats in order to easily manage package requirements. These
are examples of what can be passed:
- "package"
- ["package1","package2"]
- ("package",)
- ("package", "version")
- [("package1",)("package2",)]
- [("package1", "version1"),("package2","version2")]
This change also adds the option to install a specific version for the
puppet configuration module. This is especially important here as
successful puppet deployments are highly reliant on specific puppet
versions.

often it is convenient to classify a distro as being part of an
operating system family. for instance, file templates may be
identical for both debian and ubuntu, but to support this under
the current templating code, one would need multiple templates for the
same code.
similarly, configuration handlers often fall into the same bucket: the
configuraton is known to work/has been tested on a particular family
of operating systems. right now this is handled with a declaration
like:
distros = ['fedora', 'rhel']
this fix seeks to address both of these issues. it allows for the
simplification of the above line to:
osfamilies = ['redhat']
and provides a mechanism for operating system family templates.

the fully qualified domain name should end

fqdn to the update and set hostname methods
and using it accordingly.

helper objects.
1. Add in a parser for the /etc/hostname file that can be shared
2. Adjust the sysconfig configobj parser to not always quote
fields that it does not need to quote + add in tests around
this to ensure that we don't go nuts with quoting again.

of this function that needs to occur since
its pretty much the same now.
|

1. Move out the old helpers that provided oop access/reading/writing
to various standard conf files and place those in parsers instead.
2. Unify the 'update_hostname' which varied very little between distros
and make it generic so that subclasses can only provide a couple of
functions to obtain the hostname updating functionality
3. Implement that new set of functions in rhel/debian
4. Use the new parsers chop_comment function for similar use
cases as well as add a new utils make header function that
can be used for configuration files that are newly generated
to use (less duplication here of this same thing being done
in multiple places.
5. Add in a distro '_apply_hostname' which calls out to the 'hostname'
program to set the system hostname (more duplication elimination).
6. Make the 'constant' filenames being written to for configuration
by the various distros be instance members instead of string
constants 'sprinkled' throughout the code

Rework the rhel sysconfig writing/updating so that it goes through a
single function which helps ensure correctness. Also write to
/etc/sysconfig/network when we have written out devices to ensure that
networking is on.

then each interface is brought up individually instead
of using the '--all' which isn't on rhel. The default
debian behavior will be to use this still though as it
overrides the new bring up interfaces function for this
case.

update_package_sources on RHEL called "yum update", which actually

Previously update_package_sources was a private class
(_update_package_sources). The apt_update_upgrade class called it.
It does make sense that things would want to call this independently
of installing packages. Therefore, expose it as a non hidden method.

1. Translate (some of) the ubuntu network format to the rhel format (until we have python netcf active) and
then write the different ifcfg files to /etc/sysconfig/network-scripts as needed to bring the network online
2. Apply the hostname to the write /etc/sysconfig/network file (appending to it or adjusting that file if it exists)
3. Write to the /etc/sysconfig/clock file to adjust the timezone (or adjust that file instead of appending)
4. Runs yum commands (to match the packaging commands in the apt-get flavor)
5. Update the hostname in /etc/sysconfig/network (or a previous file) for the update hostname transform
