This fixes an occurrence of a loop variable being captured in a
parallel test (`TestInitialUpdate`). Prior to this commit, only the
last test case declared in that test would actually execute. To work
around this problem, we create a copy of the range variable before the
paralllel test, as suggested in the documentation for the `testing`
package:
https://pkg.go.dev/testing#hdr-Subtests_and_Sub_benchmarks
The test immediately after the one fixed here (`TestInvalidFile`)
followed the same pattern but correctly created a copy of the loop
variable, illustrating how easy it is to forget to do this in
practice.
Issue was automatically found using the `loopvarcapture` linter.

It's currently possible to use blackbox_exporter to probe MX records
themselves. However it's not possible to do an end-to-end test, like is
possible with SRV records. This makes it possible to use MX records as a
source of hostnames in the same way as SRV records.

This commits adds a __meta_kubernetes_pod_container_image as a new
metadata label. This can be used to alert on mismatched versions of
targets who don't have a build_info metric, as well as injecting it into
log lines for other consumers of discovery/kubernetes (e.g., Promtail).

The Kubernetes service discovery can only add node labels to
targets from the pod role.
This commit extends this functionality to the endpoints and
endpointslices roles.

The tests for Kubernetes SD rely on comparing target groups by first
serializing them to JSON. However, the target group MarshalJSON function
only serializes the __address__ label, which makes eliminates all other
labels from the comparison.
This commit implements a separate marshaling function intended for use in
Kubernetes SD tests. The function serializes all target labels, making
comparisons much more reliable. The commit also fixes all tests that
started to fail due to the newly introduced change.

This commit introduces a new metric to count the number of failed
requests to Linode's API when using Linode SD. Resolves#10672, inspired
by #10476.
_Note_: this doens't count failures when polling the `/account/events`
endpoint, as a `401` there is how we determine if the supplied token has
the needed API scopes to do event polling vs full refreshes each
interval.

* Run gofumpt on all files
Getting golangci-lint errors when building on my laptop, possibly because I have newer version of gofumpt then what it was formatted with.
Run gofumpt -w -extra on all files as it will be needed in the future anyway.
* Update golangci-lint to v1.44.2
v1.44.0 upgraded gofumpt so bumping version in CI will help keep formatting correct for everyone
* Address golangci-lint error
Getting 'error-strings: error strings should not be capitalized or end with punctuation or a newline' from revive here.
Drop new line.

The upgraded client adds order=creation_date_desc to the query
parameters causing the tests to fail. Instead of checking the full URI,
just check that the path is correct.
