[SRU] maas dhcp.conf template not adding ignore-client-uids unless using raring or later

Bug Description

1. Description of the problem:

The maas dhcpd.conf.template only adds ignore-client-uids if using raring or later. Packages in the cloud-tools archive should work on precise and require this option for dhcpd. I have verified that dhcpd starts after adding ignore-client-uids

root@maas1000:~# cat /etc/maas/templates/dhcp/dhcpd.conf.template
subnet {{subnet}} netmask {{subnet_mask}} {
       filename "{{bootloader}}";
       {{if platform_codename >= 'raring'}}
       ignore-client-uids true;
       option subnet-mask {{subnet_mask}};

No having the option enabled by default causes DNS/DHCP to misbehave when managed by MAAS. This option needs to be added when installing from CA/ cloud-pocket tools, however, in order for it to hit the CA needs to be SRu'd.

[Test Case]
1. Install maas
2. check that /etc/maas/templates/dhcp/dhcpd.conf.template has the option enabled.

[Regression Potential]
Minimal. This won't affect saucy at all, but it is required for the cloud-archive (which uses the latest from saucy).

Hi Matt,

The version of MAAS in the precise ubuntu archives does *not* support ignore-client-uids because the version of isc-dhcp in the precise archives does not support it either.

However, the maas version in the cloud-tools pocket does include the option by default, as we also ship a new version of isc-dhcp (which supports ignore-client-uids).

For this reason, I'm marking this bug invalid. If you feel this issue persists, please re-open the bug.
