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.

ref #7469. Follow up change that adds proper paging with 50 results
per page as well as a search box to search by name, login or email.

added cubic decimetre - dm3 #7695

Pass dropcounter rate option if no max counter and no reset value or reset value as 0 is specified (#7743)

This improvement allows to wrap an "expression" when using single or
double quotes. So now you can have time interval with offset for
influxdb.
