@vinylen could you please rebase against latest main? thank you.

@reta Does it look OK now?

@vinylen certainly, we'll do 2.0.1.0 release and move on with this one right away, thanks a lot!

this isn't working yet, see the failed build:

[..]
Welcome to Gradle 6.8.3!
[..]
* What went wrong:
A problem occurred evaluating root project 'prometheus-exporter'.
> Failed to apply plugin class 'org.opensearch.gradle.info.GlobalBuildInfoPlugin'.
   > Gradle 7.4.1+ is required
[..]

so a gradle major release upgrade is in order first 😢

i took a quick stab at this and it turned out to be relatively easy: see #77
i briefly tested it and can confirm that with #77 it then also works to bump the version to 2.1.0.0 and accordingly build against OpenSearch 2.1.0.

@vinylen apologies, mind doing another rebase? thank you :)

Should be good to go now @reta

LGTM. I can squash all three commits and merge.

LGTM.
IMO we should have only a single commit but we can squash them from GitHub UI when merging.

Are you planning to make a release for this one?
