file: add support for sensitive files

[terceiro]

sensitive files will not get changes to their contents logged.

@terceiro That's a good idea. In my opinion, print "diff existing but not show content because it's sensitive" in show_content_diff is more friendly. What do you think about it? 👀

	def show_content_diff
	if attributes.modified
	Itamae.logger.info "diff:"
	diff = run_command(["diff", "-u", compare_to, @temppath], error: false)
	diff.stdout.each_line do |line|
	color = if line.start_with?('+')
	:green
	elsif line.start_with?('-')
	:red
	else
	:clear
	end
	Itamae.logger.color(color) do
	Itamae.logger.info line.chomp
	end
	end
	runner.handler.event(:file_content_changed, diff: diff.stdout)
	else
	# no change
	Itamae.logger.debug "file content will not change"
	end
	end

@unasuke yes I agree, that is better. Modified the PR accordingly.

@terceiro Sorry, late. I checked changes and behavior on my local machine. It's looking good to me.
