[Improvement] PipelineCaching: provide a mechanism to upload and download cache at specific times

Type: Feature, Improvement

Enter Task Name: Cache@2, Azure Pipelines

Issue Description

My job processes many build variations, but bc of the software I’m using the cache is located in the same folder for each platform I’m building to. I’d like to have a mechanism to trigger when the post build cache event uploads the cache.

for example:

- ${{ each target in parameters.targets }}:
  - ${{ each validTarget in parameters.validTargets }}:
    - ${{ if eq(target, validTarget) }}:
      - task: CacheDownload@0
        inputs:
          key: '"cache" | "$(Agent.OS)" | "${{ target }}"'
          path: 'cacheFolder'
      - template: steps/run-tests.yml
        parameters:
          target: ${{ target }}
      - template: steps/build.yml
        parameters:
          target: ${{ target }}
      - task: CacheUpload@0
        inputs:
          key: '"cache" | "$(Agent.OS)" | "${{ target }}"'
          path: 'cacheFolder'

#13194 has silently been closed. This one and that have similar intentions, but different approach. I agree that we need this feature, whatever approach is used.

I personally prefer the other one, but this one is still open. So maybe this one is the preferred one by the developers?

nope, it’s not published but I realized it’s never gonna happen
