Add two data series-level options "negweight" and "posweight" that
will use the numerical value of the data instance name
as the sorting factor. This enables e.g. sorting by CPU frequency
in the cpufreq module.
Add new graph-level option "ordercolor" to use colorsfrom a
pre-defined color table for the data series. This enables keeping
similar colors for similar data series in different plugin instances.
E.g. CPU frequencies in several cores that are handled and displayed
separately.
(note: the table has 8 items and if there are more series, it uses
the same colors again. The table can be easily extended/modified)

Fixes situations where RRD file name contains ":" (eg. _ping/ipv6_) in `rrdtool` it's unescaped - thus not able to render image. Adding simple escaping of `:` to `\\:` fixes the situation.
Might be a solution for #958.
Added configuration parameters to also configure the height of the rrd images.
config statistics 'rrdtool'
option image_height '200'

: is used to delimit fields in DEF: rrd instructions, so when it appears
in a filename it must be escaped using \.[1] This commit adds the
escaping.
I discovered the issue after configuring collectd-mod-ping to monitor an
IPv6 host (2001:19f0:5:727:5b56:205d:ff55:2208). Accessing
https://192.168.0.1/cgi-bin/luci/admin/statistics/graph/ping would cause
the following messages to be logged:
Wed Nov 14 23:04:33 2018 daemon.err uhttpd[30261]: ERROR: can't parse DEF '2ping_avg_raw=/tmp/rrd/openwrthost/ping/ping-2001:19f0:5:727:5b56:205d:ff55:2208.rrd:value:AVERAGE' -2

and the graphs would not display. After applying this commit, the
graphs display correctly and no messages are logged.

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.

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".
