The print_stall logic could cause large portions of the graph to show
up as 100% host utilized. Rework the logic to avoid that.

Use an alpha transparency on each of the stats, so that it is possible
to see how the values overlap.
Also, always enable the "awake time" stat - just use a lower alpha
transparency for it.
Also, explicitly set the graph size as some version of matplotlib have
a different default.

Update the mechanism to filter out cases where buffer_time is below
MAXBUFFER so that it works with the statistics currently generated.

Matplotlib will try to open a display by default - tell it not to do
that so that it can run in batch mode on headless machines.

Update the graphstats.py graphing script so that it works with recent
stats changes - the stats can now contain groups that end with a ':'
and the print_time is no longer reset to zero on a new print.

Now that tasks are only run when needed it's common for there to be a
larger variation in task execution time. When graphing load, consider
a 99-percentile task duration of 2.5ms to be 100% loaded (up from
1ms).

Some systems point python to python3 instead of python2 - explicitly
request python2 to avoid conflicts.

Change the lookahead queue so that it attempts to buffer at least
buffer_time_high amount of moves when first starting a print. This
helps ensure the buffer is normally always full.
If the buffer falls below buffer_time_low then it is either due to the
end of a print or because octoprint/klippy is unable to keep up.
Change the code so that in this case the lookahead queue will attempt
to gather buffer_time_high amount of moves before restarting movement.
Update the default buffer_time_low to 1 second and buffer_time_high to
2 seconds. With the above changes a smaller buffer_time_high and a
larger buffer_time_low are more practical.
