Support bursting on GKE cluster with initial version 1.18.17-gke.100

[Rajatj21]

Based on the documentation
https://cloud.google.com/kubernetes-engine/docs/how-to/pod-bursting-gke

It says any gke cluster created with version prior than 1.26 can't use bursting, my cluster was created on 1.181.17 version.

But I'm consfused by one of the line
```

Pods that use the Performance compute class or the Accelerator compute class can burst in any GKE version that supports that compute class.
```
Which is the performance compute class. Does it mean, its same as https://cloud.google.com/kubernetes-engine/docs/how-to/performance-pods#one-pod-per-node meaning 1 node per pod

Can someone help me with this

Yeah, it's the one-pod-per-node one. We'll update the bursting doc to make that clearer

[Rajatj21]

Okay. Thanks for the clarification

Just following up, it's for whenever you select a specific machine series (doesn't matter if you also ask for one Pod per node). We updated the doc to say so: https://cloud.google.com/kubernetes-engine/docs/how-to/pod-bursting-gke#availability-in-gke
