get_interfaces: don't exclude bridge and bond members
The change that introduced this issue was handling interfaces that are
bonded in the kernel, in a way that doesn't present as "a bond" to
userspace in the normal way. Both members of this "bond" will share a
MAC address, so we filter one of them out to avoid incorrect MAC address
collision warnings.
Unfortunately, the matching condition was too broad, so that change also
affected normal bonds and bridges. This change specifically excludes
bonds and bridges from that determination, to address that regression.

Add support for Arch Linux in render-cloudcfg
- Detect Arch Linux and set variant accordingly in `system_info()`
- Allow setting render-cloudcfg variant parameter to 'arch'
- Adjust some basic settings for Arch Linux in the cloud.cfg.tmpl
The template might need some additional Arch-specific tweaks in the
future, but at least for now the generated config works and contains
the most relevant modules.
Also:
- Sort distro variant lists when adding Arch
- Add debian to known variants in render-cloudcfg
ovf: do not generate random instance-id for IMC customization path
Cloud-init will not operate properly if the instance-id value changes
on each boot. This is the source of a number of behavioral bugs filed
against cloud-init with OVF datasource. Instead, use a static instance-id
value, iid-vmware-imc, similar to iid-dsovf.
sysconfig: only write resolv.conf if network_state has DNS values
If an OS image provided an /etc/resolv.conf file that was not empty
cloud-init would read and re-write it with a cloud-init header even
if no DNS network configuration was provided (e.g. DHCP only).
This can cause problems for some network services which don't
ignore cloud-init's header.
sysconfig: use distro variant to check if available
The sysconfig renderer used the distro name directly which mean
some variants of distros were not considered supported. Fix this
by using util.system_info()['variant'] instead. Fix the list of
KNOWN_DISTROS value for redhat -> rhel.
