[PATCH 3/3] testbot: Add a Munin plugin to monitor the TestBot activity.

This will make it possible to compare current data to historic data for
crucial parameters like the number of jobs and tasks per hour, the job
completion time, each VM host's busy rate, etc.
It will also make it possible to see if the reverts are progressively
getting slower, or if on the contrary they got slower on a specific
date, which would point to some change on the host, etc.
Note that access to the new Munin web page requires an API key to limit
who can query these statistics.

To enable the Munin interface, set MuninAPIKey in ConfigLocal.pl. For
instance you can pick a value from the output of 'pwgen 20'. Then send
me that value privately and I'll set up the Munin plugin part.

+
+Analyses the activity of the recent past, computes the corresponding metrics
+to be tracked by Munin, and prints the Munin configuration and data on stdout.
+
+Note that defining how far back to go to compute the Munin metrics is tricky.
+
+Munin collects data every 5 minutes so if can be tempting to report on what
+happened in the past 5 minutes. However we have to report on infrequent events:
+- New jobs arrive infrequently: around one per hour currently, and it is
+ not rare for two of them to arrive at the same time. If we were to naively
+ extrapolate 1 new job in the past 5 minutes as a rate of 12 jobs per hour
+ we'd get a graph with exagerated swings. But note that things would converge
+ on a meaningful value as Munin averages things out for the monthly or yearly
+ graphs.
+- We could instead record when the last job arrived and derive a rate by
+ dividing the number of new jobs by that interval. For instance assume the
+ rate is 4 jobs/hour, at precisely 15 minutes intervals. So over the course
+ of an hour we will report a rate of 4 jobs/hour 4 times, each time the
+ result of 1 / 15 * 60, and a rate of 0 the 9 other times. But when Munin then
+ goes on to average these, for instance for the monthly graph, it will get
+ an hourly rate of 1.3 job/hour = (4*4 + 9*0) / 12, which is wrong.
+- Another approach to the above problem would be to not graph a rate but
+ simply the number of new jobs in the given period. However the rate is much
+ more meaningful. 4 jobs/hour means the TestBot must complete jobs in under
+ 15 minutes to keep up. But figuring out the rate from a graph of the raw new
+ job count would be quite a bit harder for the administrator.
+- For the VM operation times (like revert times), chances are that over a
+ 5 minutes period there is nothing to report, so the value is 'undefined',
+ 'U'. This results in dashed lines: one short dash for a 5 minutes period and
+ then nothing for the next hour. The shorter the period, the shorter and more
+ widely spaced the dashes, making the graph hard to read.
+- When no data is available in the chosen period, we could also report the
+ last value for that operation. For instance if a revert took 15 seconds,
+ report 15 seconds until a new revert occurs, thus avoiding the dashed line
+ issue. However how long should the last value be reported? Also seeing a
+ continuous line for the offline time one could think it means the VM is
+ frequently being marked offline.
+
+Taking all this into account, GetOutput() analyzes the past hour.
+- This gives meaningful hourly rates.
+- And where there are intermittent values the dashes are long enough.
