[MIR] pyyaml

[Scott Moser]

Rationale:
 * python-yaml is a new runtime dependency of ec2-init
 * the dependency was added in development of blueprint server-lucid-ec2-config
Security:
 * No open or recent security issues
Quality:
 * Open bugs (1 debian, 0 ubuntu)
   http://bugs.debian.org/cgi-bin/pkgreport.cgi?package=python-yaml
   http://bugs.debian.org/cgi-bin/pkgreport.cgi?src=pyyaml
 * Test suite does run on build
 * actively maintained
Dependencies:
 * depends on libyaml-dev (libyaml) [MIR bug 516930]
Standards compliance
 * very standard package for a python package
Maintainence:
 * well maintained in debian, not likely much need for extra work
Background information:
 pyyaml provides a python module for reading and writing yaml. It is useful for human readable and writable configuration files or other structured data. ec2-init began using the python-yaml library as a syntax for the "cloud-config" data.

Possibly worth noting that the Debian maintainer is somewhat active in Ubuntu.
