Clearer template errors should be given during build review

Description
When putting a machine in build mode, if there is an error in the template the error message is very vague, like "Failure parsing <template name>: undefined method `<' for nil:NilClass.".
This makes debugging very hard. The error message should at least contain the line number for the line causing the error.

Error messages could be improved by using macros, that would have explicit checks on objects. There was a discussion on foreman-dev list recently that suggested using proxy objects on which we'd define such macros. The line number is technically possible only with safe mode disabled, #18432 adds this to the log at least.
