Determine machine size in juju programitcally

I wouldn't call this easy, but it works, and it keeps me out of python.

# on hpcloud

$juju status apache2 2>/dev/null | grep instance-id |
  awk '{split($0,array,":")} END{print array[2]}' | tr -d ' ' |
  xargs nova show | grep flavor |
  awk '{split($0,array,"|")} END{print array[3]}' | tr -d ' '
