Fixes#5515. Flot gauge has its own threshold check that is different
from the threshold check in singlestat. This changes the flot check to
be exclusive (same as the singlestat check). E.g. if the threshold is
10, then the value 10 is over the threshold.

this was caused by too often fired mouseenter/mouseleave events

When table data returns a column with the value 0, it should not ignore
it. This change checks for undefined instead of if the value is truthy.
Fixes#8531
If there are too many ticks generated for the y-axis (which can occur
for log scale 2, with a small y-min and a large max), then the ticks
will be regenerated using larger jumps between the ticks.
This also handles the case when y-min is set to 0. Previously, y-min of
0 was ignored as zero is not a valid value for log scale. Now the tick
generator approximates zero by setting min to 0.1.
Ref #8244
Ref #8516
fixes#8446. Data with all values equal to zero, creates a max with the
value of Infinite. The for loop for creating ticks then gets stuck in an
infinite loop. This fix resets min and max and creates some fake ticks
for the y-axis if the min and max are not finite numbers.
The bug was happening because the background color was being based on
the rounded value (accounting the user defined decimals). Changed it to
use the pure value (not the rounded) to follow whats being done in the
value color, and also in the table thresholds (they don't consider the
decimals when comparing to thresholds).
Avg column was being added at every rendering, if the table was empty.
Now the column will be added once as an initialization when selecting a
'timeseries_aggregations' transform.
