@blakerouse @urso WDYT about disabling ARM packaging for elastic-agent for now?

[urso]

We do provide ARM packages for download. The build issue MUST be fixed properly. I'm not too keen to disable building, but if we can't fix it ASAP we might want to disable the ARM packaging job for PRs only. Master and 7.x should still fail on it.

but if we can't fix it ASAP we might want to disable the ARM packaging job for PRs only. Master and 7.x should still fail on it.

Then, it requires further changes in the CI to support only branches and tags.

1. beats/x-pack/elastic-agent/Jenkinsfile.yml

   Lines 98 to 104 in 2ebf83e

   	packaging-arm:
   	packaging-arm: "mage package"
   	e2e:
   	enabled: false
   	platforms: ## override default label in this specific stage.
   	- "arm"
   	stage: packaging

   should be something like:

    packaging-arm:
        packaging-arm: "mage package"
        e2e:
            enabled: false
        platforms:             ## override default label in this specific stage.
          - "arm"
        stage: packaging
        when:
            branches: true     ## for all the branches
            tags: true         ## for all the tags

2. beats/.ci/packaging.groovy

   Lines 390 to 401 in 2ebf83e

   	def release(){
   	withBeatsEnv(){
   	withEnv([
   	"DEV=true"
   	]) {
   	dir("${env.BEATS_FOLDER}") {
   	sh(label: "Release ${env.BEATS_FOLDER} ${env.PLATFORMS}", script: 'mage package')
   	}
   	}
   	publishPackages("${env.BEATS_FOLDER}")
   	}
   	}

   
   should be changed to filter (BEATS_FOLDER == 'x-pack/elastic-agent' && ! isPR()) in order to do nothing.

Lets merge this so the build is green will followup with that in priority.

PRs are blocked for a few days. Let's make progress here. The ARM packaging should be restored ASAP in a follow up PR.

I think this issue will impact E2E tests running on ARM workers, where we use the elastic-agent ARM image for the stand-alone mode test scenarios. cc/ @EricDavisX
