Currently we're hardcoding `job="prometheus-k8s"` as selector. This
doesn't work if your prometheus is elsewhere. Fortunately we have
`prometheusSelector` in `$._config` which all the other alerts use.
Use that here too.

* Prettifier: Add spaces with non-callable keywords
I prefer to have a difference between, on one side: functions calls, end(), start(), and on the other side with, without, ignoring, by and group_rrigt, group_left.
The reasoning is that the former ones are not calls, while other are
functions. Additionally, it matches the examples in our documentation.

We print the stacktrace of a panic when query causes one, but there's no
information about the query itself, which makes it harder to debug and
reproduce the issue.
This adds the 'expr' string to the logged panic.

The examples were still depending on an ancient prometheus
version. Updating caused some dependency shenanigans, but this should
work for now.

* Shortcut Matrix.ContainsSameLabelset()
It's quite often to execute this check on a Matrix that has zero or only
one series. There's no need to allocate a map for those cases.
There's also a one-liner for two-series case, so why not using it?

- For now this is relatively simplistic, but at least acknowledges some

* Implement Pretty() function for AST nodes.
Signed-off-by: Harkishen-Singh <harkishensingh@hotmail.com>
This commit adds .Pretty() for all nodes of PromQL AST.
Each .Pretty() prettifies the node it belongs to, and under
no circustance, the parent or child node is touch/prettified.

* Refactor functions between printer.go & prettier.go
Signed-off-by: Harkishen-Singh <harkishensingh@hotmail.com>
This commit removes redundancy between printer.go and prettier.go
by taking out the common code into separate private functions.
* Add more unit tests for Prettier.

* Add support for spliting function calls with 1 arg & unary expressions.
Signed-off-by: Harkishen-Singh <harkishensingh@hotmail.com>
This commit does 2 things:
1. It adds support to split function calls that have 1 arg and exceeds the max_characters_per_line
to multiple lines.
2. Splits Unary expressions that exceed the max_characters_per_line. This is done by formatting the child node
and then removing the prefix indent, which is already applied before the unary operator.
* Removing global state modification on unit tests (fix#10033#10034)
The config.DefaultRemoteReadConfig and config.DefaultRemoteWriteConfig
instances hold global state. Unit tests were changing their url.URL reference
globally causing false positives when tests were ran through package.
Two helper functions were created to copy those global values instead of changing
them in place to fix null point when running unit tests by method instead of
by package.

Bryan did reduce the sleep time improving the deltas on the benchmark by
quite a lot. However I've been working on a similar implementation for
out of order and I noticed that we actually get into this method
thousands of times.
@ywwg had the brilliant idea of not always sleeping before the select
but actually make it a case in the select so we only sleep if we need
to.
The benchmark deltas are amazing
