add initial logging support

This logging infrastructure in cloudinit:
- uses python logging
- allows user supplied config of logging.config.fileConfig format to be
  supplied in /etc/cloud/cloud.cfg or in cloud_config by user data.
- by default, tries to use syslog, if that is not available, writes directly to
  /var/log/cloud-init.log (syslog will not be available yet when cloud-init
  runs)
- when using syslog, the doc/21-cloudinit.conf file provides a rsyslogd
  file to be placed in /etc/rsyslog.d/ that will file [CLOUDINIT] messages
  to /var/log/cloud-init.log
