Preserve indentation in policy_templates.json

Currently all leading spaces are stripped from the policy description
text - this leads to hard-to-read JSON examples. This change keeps
the indentation that is useful to users, but strips the common 6-space
indentation that is there only to make policy_templates.json itself
more readable.

See bug for screenshot of this change.
