Run stopSidecar logic even if TaskSpec has no sidecars to support injected sidecars such as istio-proxy

Run stopSidecar logic even if TaskSpec has no sidecars to support injected sidecars such as istio-proxy

Signed-off-by: Sascha Schwarze schwarzs@de.ibm.com

Changes

Sidecars in a Tekton pod can be declared in the TaskSpec, but could theoretically also be injected by a webhook, such as the istio-proxy.

The logic in stopSidecars was optimized to omit loading a Pod unnecessarily. But that did not honor the webhook-injected sidecars.

I am changing the logic to only skip the stopSidecars logic if the running-in-environment-with-injected-sidecars feature flag is set to false (default is true).

Still need to work out the unit test.

/kind bug

Fixes #4731

Hi @SaschaSchwarze0. Thanks for your PR.

I'm waiting for a tektoncd member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
