As part of the ceph-ansible project, this change was put in:
ec042219e6
This was to handle the case where the config would change, initiating a
restart handler, even though no actual change happened.
We can juse use sorted() since we are passing back a list with .items()
which can then be sorted.
The above change didn't include a change to ensure the order of the
sections, which meant that although the individual items were sorted the
sections could change order causing unnecessary changes.
Additionally, this adds a test to retemplate the file 3 times, with a
lot more sections to ensure the order remains the same, this will fail
when the config template changes even though no changes have happened.
