Title: Determine Graphite Check Range by Frequency

I was having a problem checking metrics that update less frequently than the default 10 minutes.

I could have increased the global GRAPHITE_FROM but I preferred the range to be determined by the check's frequency.

This PR also makes the metric preview graph show the correct range as the frequency is modified.
