Scott Moser 89679670fb rework package mirror selection ... 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.		2012-08-22 00:28:29 -04:00
