Export pre-conversion report to txt file

The Satellite pre-conversion analysis job template (RHELC-1012) needs to be able to print the pre-conversion analysis report file to the user. Right now Satellite can just capture STDOUT. It'd be ideal if we print the report to a txt file and the Sat job prints and greps it - this approach has been consulted with rhn-engineering-mhulan.

Acceptance criteria:

• the messages are sorted based on priority
• there's no special formatting we need to follow
• we switch off color coding
• we don't need to filter the results - we can include successes
• no need to document (prod doc) that we now generate the txt file
