Renato Costa d521933053
Fix incorrect use of loop variable in parallel test (#11205) 
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.

Łukasz Mierzwa 3196c98bc2
Reduce memSeries memory usage by decoupling metadata (#11152) 
Metadata was added recently but doesn't seem to be used much, at least as far as I could identify.
Yet it's part of memSeries struct and so even when empty takes 48 bytes,
which is a lot given that without it memSeries requires 224 bytes.
This change turns it into a pointer on the struct, that get set only when metadata is actually set of given series.

Chris Sinjakli fba20567c0
Document permissions needed for ec2_sd_configs (#11119) 
Currently, it's not explicitly called out which permissions are needed
for service discovery of EC2 instances. It's not super hard to figure
out, but it did involve a bit of guesswork when I did it yesterday, and
I figure it's worth saving people that effort.

I've also seen examples around the internet where people are granting
much broader permissions than they need to, so maybe we can save on that
by explicitly saying what's needed.

Support using MX records for DNS discovery (#10099) 
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.
