Make Prometheus query field a textarea #7663

This is an old PR so had some problems after merging in master.

- Fix for min and max that were not getting passed into the
applyLogScale function
- Fix for when min/max were undefined rather than null
- Fix for decimal ticks, as this PR populates the ticks itself then
it also needs to calculate the number of decimal places too. Flot
was showing the wrong number of decimal places sometimes otherwise
on the y-axis.

Small fix for the "glow" when focus the field for LIMIT and SLIMIT

when checking if rendering a png for lazy loading of panels.

Included LIMIT, SLIMIT and ORDER BY time for influxdb. closes #6065 and closes #7232

* (prometheus) adjust annotation step

* (prometheus) add step option

Moves the logic up a level to the panel_ctrl. This cleans up the code
and makes the lazy loading available for all panels.

Removes the config option and making this default behavior. We can
add back the config option if we get feedback that it is needed during
the beta phase of the v4.3.0 release.

Unbind the scroll handler on panel destroy to avoid memory leaks.

Fix for png rendering, it did not match all forms of dashboard-solo.
e.g. /render/dashboard-solo/db...

Fix for when taking a snapshot. All the panels get refreshed then
even the panels that are not visible.

Closes #5216.
