Fix config_template to consistently order sections

In ec042219e6 we added OrderedDict and
sorted to be able to preserve order for config_template k,v pairs inside
a section.

This patch adds a similar ordering for the sections themselves, which
could still change order and intiiate handler restarts.

OrderedDict isn't needed because we use .items() to return a list that
can then be sorted().
