Example test case to showcase using Patch Resources and field ownership conflicts

[rquitales]

TestIgnoreChangesPatchResources tests that we can successfully ignore changes to a Patch Resource without SSA conflicts, and accidentally unsetting a field of interest when the Patch resource is declared as the field manager. This allows a user to use a SSA Patch resource like a strategic merge patch resource.
This test uses 2 stacks:

1. The "deployment stack" creates a Deployment object on cluster.
2. The "patch stack" uses a DeploymentPatch resource to patch the Deployment object on cluster.

Steps:

1. Create the deployment stack and let it run in the background with a goroutine.
2. Wait for the deployment stack to finish creating the deployment object.
3. Create the patch stack and patch the deployment object to scale to 2 replicas and have shared field
   owner ship of the .metadata.labels.app field.
4. Validate that the deployment was scaled to 2 replica.
5. Unblock the last step of the deploymnet step to run, and block the second step of the patch stack from running.
6. Run the second and final step of the deployment stack to relinquish field ownership of the .metadata.labels.app field
   to the patch stack.
7. Unblock the second step of the patch stack to run.
8. Run the second step of the patch stack, which we expect to fail.
9. Add the .metadata.labels.app field to the ignoreChanges list of the DeploymentPatch resource in step 3 of the patch stack.
10. Run the third step of the patch stack which we expect to succeed.
