* 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
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.

Updates the docs to work with the website repo - mainly
relative link updates.
Adds a menu.yaml file to build the sidebar menu (no longer
using front matter weight).
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.
* Update README.md
Capitalized the G and S in "Getting Started," and moved "guide" to match the section title in the docs.
* Fixed sentence structure. Changed "download" to "grafana.com/get" and changed "get" to "download".

* Graph: constant series as override
- ability to define a series override that takes the first value of a
timeseries and produces constant series from it.
* Moved constant series override logic to grafana-ui
* Added docs for instant queries and constant series override
* Fix: Upgrade hugo wip
* Chore: Rename index to _index for latest hugo
* Chore: Use relative refs, no starting slash

Fixes#16507
Markdown formatting in VS Code converts from asterisks to underscores but this can be incorrect
in a case like _label_names()_. This fix escapes the underscores that should be kept.
- future alignment cause issues with rate charts and the display of last
values
- this change modifies the alignment to use the last available aligned
end date and no longer possibly requests data from the future
Alerting for prometheus have been depending on the step parameter from each query.
In https://github.com/grafana/grafana/pull/9226 we changed the behavior for step in the
frontend which caused problems for alerting. This commit fixes that by introducing a default
min interval value so alerting always have something to depend on.
closes#9777
