It could be that there are also 'dhclient6.leases' files in /var/lib/dhcp
when DHCPv6 is used next to DHCPv4.
This patch makes sure we only read from DHCPv4 lease files

if the Datasource does not have an entry in config, then
set it to be a empty dictionary rather than None.
Also remove places that did this elsewhere.

Different versions of the CloudStack password server respond
differently; wget handles these nicely for us, so it's easier to just
use wget.

There might be some CloudStack deployments without the :8080 password
server, and there's no reason the rest of the data source can't be used
for them.

This seems cleaner, to avoid duplicate '/' being added.

Changes in revision 753 broke cloud-init on ubuntu, as it has a different
dhclient directory than Fedora where the change was developed and tested.
This change does 2 things:
* searches multiple directories (including /var/lib/dhcp) for the lease
files.
* adds a fallback to the old code path of choosing the default route
as the virtual router if there were no virtual routers found in the
lease files.

In CloudStack's documentation, it is stated that meta/user-data can be
retrieved from CloudStack's Virtual Router [1].
However, cloud-init retrieves these information from default gateway. VR
and default gateway may be the same machine (i.e. have the same address)
in some cases, but that is not be always true (actually, in my case, it is
not).
This change searches the lease files in /var/lib/dhclient to pick out
the dhcp-server-identifier.
It admittedly does make this specific to dhclient.

are used that lazily load the metadata from the
ec2 metadata service.
1. Add a ec2_utils module that checks which version
of boto is being used and under the right versions
the metadata dictionary will be expanded.
2. Use this new ec2_utils module in the cloudstack and ec2
datasources as there entrypoints into boto.

make pep8 now is silent on precise's pep8 ( 0.6.1-2ubuntu2).

There are several changes here.
* Datasource now has a 'availability_zone' getter.
* get_package_mirror_info
* Datasource convenience 'get_package_mirror_info' that calls
the configured distro, and passes it the availability-zone
* distro has a get_package_mirror_info method
* get_package_mirror_info returns a dict that of name:mirror
this is to facilitate use of 'security' and 'primary' archive.
* this supports searching based on templates. Any template
that references undefined values is skipped. These templates
can contain 'availability_zone' (LP: #1037727)
* distro's mirrors can be arch specific (LP: #1028501)
* rename_apt_lists supports the "mirror_info" rather than single mirror
* generate_sources_list supports mirror_info, and as a result, the
ubuntu mirrors reference '$security' rather than security (LP: #1006963)
* remove the DataSourceEc2 specific mirror selection, but instead
rely on the above filtering, and the fact that 'ec2_region' is only
defined if the availability_zone looks like a ec2 az.

2. Adjust comment on sources list from depends
3. For the /etc/timezone 'writing', add a header that says created by cloud-init

1. This is very useful for testing (until we have boto timeout in a more sane manner)
