All counter based graphs inside the the Swift dashboard are fixed
and now correctly showing the timings per second rather than total
values per telegraf flush interval.
Additionally the High Response Time graphs are now using the timing_upper
metrics.
Minor issues inside the playbook-influx-telegraf.yml and telegraf.conf.j2
are fixed to support deployments without optional componentns like ironic,
cinder etc.
