Introduce option that enables the user to select max values
instead of averages for graphs if the user has disabled RRAsingle.

The option defaults to average values, which have been the default
in Luci statistics.

Remove 'optional' from RRASingle, as it is a key option for statistics.

With rrdsingle the average values are used for graphing. As the
timescale increases (say over a day or month) the average values
progressively reduce.  Using the maximum value over the longer periods
is arguably no less deceptive but it does produce more informative
graphs.

Remove the usually empty standard deviation graph from the ping page.

The graph is empty for most users as collectd measures standard deviation
of individual pings inside the general interval of statistics collection.
Default setting for both ping interval and general collection interval
is 30s in Luci statistics, meaning just 1 ping per interval, which
leads to empty graph.

(To provide relveant data, the ping interval should be 1/4-1/5 of the
general collection interval. Even then the graph does not look very
informative due to different scaling than the latency graph.)

Note that this commit does not change collectd itself, which continues
to collect and calculate also the std.dev. data, which can be fetched
with 'rrdtool' if needed.

If a plugin produces only one instance, e.g. netlink with just one interface
configured, then the controller will register no detail views which would
normally show all graphs but the index pacage of a given plugin will still
display the collapsed view without any possibility to reach the full listing.

Fix the problem by only rendering a linked index view when more than one
instance is present.

Reorganise the menu items of the Luci statistics module:

* Re-label "Collectd" to "Setup" and place it after the "Graphs" items.
  - "Graphs" is used much more frequently so it should be first.
  - Change "Collectd" menu item to "Setup" to clarify things.

* Re-label "System plugins" to "General plugins" to change sorting.
  "Network / Output / System" changes to "General / Network / Output"
  that is more logical order for the items.

Implement support for alternative scaling of the y-axis.
By default, rrdtool will autoscale to 1,2,5,10,20,50,100,200,... etc.,
which is not always suitable (e.g. memory charts for device with 128 MB).

Rrdtool 1.0.50 already supports alternative autoscaling that creates
a tighter y-axis. Implement graph-level options in Luci statistics to
support those boolean options as "alt_autoscale" and "alt_autoscale_max".

CPU plugin in the Luci statistics was missing the label definitions,
so the field labels are like "cpu_system" instead of "System".
Add proper label definitions to CPU (like the other plugins already have).

The statistics graph was also missing softirq and interrupt stats, although colors
for them were defined. Softirq consumes massive amount of CPU especially with
any qos in use, so it is important for the user to see also that data. Add both
softirq and interrupt stats to the graph.

Earlier update to collectd 5.4.1 changed the field from "ping" to "value",
which was changed in the graph definition here, but the label definition
was forgotten. Field's label now reads "ping_IPaddr_value".

Collectd 5.5.0 introduced new data to conntrack plugin:
In addition to the number of tracked connections there is also
the static max conntrack value and the calculated use percentage.

Luci's conntrack plugin intrepretes "conntrack-max" as a new data instance
and includes it in the graph in addition to the real "conntrack" number.

Eliminate "max" from graph by specifying empty "" instance as data source.
