* Make $__range more precise in Prometheus
It is now always equivalent to `${__range_s}s`, rather than rounding
down to an integer multiple of the biggest possible unit. For example,
a range of 47 hours is now represented as `169200s` rather than `1d`.
Closes#21689.
* Update a unit test to match new __range calc
* Add info about meta data labels
* Add part about auto period calculations in cloudwatch
* Minor adjustments
* Updates after feedback
* Add more context
* Clarify what a metadata label is
Besides minor language corrections, this tries in particular to
provide some clarity about the `step` setting in the Prometheus range
query and the `$__interval` variable:
- First of all: They are both always the same.
- What's really confusing (and arguably really un-helpful) is that the
_Min time interval_ is multiplied by the resolution
factor. Therefore, I just state the fact here now but don't add
anything like "This should be the scrape interval" because it is not
true (if resolution is `1/10`, a meaningful _Min time interval_ is
generally a tenth of the scrape interval).
- More helpful is the _Min step_ parameter, because it is not
multiplied by the resolution factor (which I have now stated
explicitly). Of course, the _Min time interval_ has to be set to
something small so that the _Min step_ parameter can kick in.
It would be good if we could also override the _Min time interval_
tool tip because that is where most people will look, and the current,
very Graphite-centric tool tip is very confusing for the Prometheus
query editor, in particular because it doesn't have any hint about the
resolution factor being applied. See #21413.

In the data sources docs two similar subsection names were used.
This PR renames `Adding the data source to Grafana` subsection to
`Adding data source` so that all data sources have the same
subsection name.

It is now possible to specify a field containing time-end in
Elasticsearch annotations.
Any annotations with a time-end will become a region between
time and time-end. Any annotations without the time-end field
will remain a single-point annotation.
