BUG issue with deploying maintenance file [do not merge]

This fixes a syntax error in the maintenance.rb file, as well as removes hardcoding on the location of maintenance templates.

Do not merge until reviewed and demonstrated to not cause regressions in any environment deploynaut is already used in.
