seperate affinity assistant setting on workspace

[lookis]

Feature request

Config affinity assistant on each workspace override default setting in feature-flags

Use case

I've got same problem with this issue: #3480

In my case, I have a PVC for code, and another PVC for build cache, and I will use a NAS StorageClass for cache PVC which will share data across AZs.

the code PVC will share between different task, such as git-clone-task and build-task, so this PVC needs affinity assistant

for now, if I set disable-affinity-assistant to true globally:

1. code PVC with normal PV may failed if tasks schedule to different node,
2. code PVC with nas PV need to clean up every time build-task done.

if I set disable-affinity-assistant to false globally:

• cache PVC will not work (for more than one PersistentVolumeClaim is bound)

and If i can set code PVC to use affinity assistant, and disable cache PVC's affinity assistant, every thing works! and we just need to raise error if more than one affinity assistant exists.

/remove-lifecycle stale
We have the same issue. We want to use AWS EFS as a build cache, but also use another ephemeral PVC for the usual workspace.

@lookis @icereed your use case should now be addressed by the new "coscheduling" feature, which allows all of a pipelinerun's pods to be scheduled to one node, and multiple PVCs to be bound to a single taskrun in a pipelinerun. We'd appreciate if you can share any feedback on #6990!
