feat(action): add create new action for compatibility testing

[DexterYan]

• add a new action to create a cmx cluster for compatibility testing
• add helm-extra-repos input

      Example:
      helm-extra-repos: |
        - repo_name: "cnpg"
          url: "https://cloudnative-pg.github.io/charts"
          namespace: "cnpg-system"
          chart_name: "cloudnative-pg"
        - repo_name: "minio-operator"
          url: "https://operator.min.io"
          namespace: "minio-operator"
          chart_name: "operator"

an example to use this action

      - name: Create Compatibility Testing
        id: create-compatibility-testing
        uses: replicated-collab/replicated-actions/prepare-cluster@main
        with:
          app-slug: ${{ secrets.REPLICATED_APP }}
          api-token: ${{ secrets.REPLICATED_API_TOKEN }}
          chart: ${{env.chart_name}}-${{ github.event.inputs.version }}.tgz
          kubernetes-distribution: ${{ matrix.cluster.distribution }}
          kubernetes-version: ${{ matrix.cluster.version }}
          helm-chart-name: ${{env.chart_name}}
          namespace: test-${{env.chart_name}}
          helm-run-preflights: false
          helm-extra-repos: |
            - repo_name: "cnpg"
              url: "https://cloudnative-pg.github.io/charts"
              namespace: "cnpg-system"
              chart_name: "cloudnative-pg"
            - repo_name: "minio-operator"
              url: "https://operator.min.io"
              namespace: "minio-operator"
              chart_name: "operator"

Is this different from the cluster prepare action? Is it the case that the only difference is the helm-extra-repos. If that is needed (not sure), maybe we can improve cluster-prepare?

That's a good idea. Let me add it to cluster-prepare

[DexterYan]

Hey @jdewinne I have updated the PR to keep it in cluster-prepare

[jdewinne]

Should this also include

if: ${{ inputs.helm-extra-repos != '' }}

[DexterYan]

good catch. I have added it
