Pod Disruption Budget isn't created for cluster agent

[ylee-figma]

Output of the info page (if this is a bug)

❯ k get datadogagents.datadoghq.com
NAME      AGENT             CLUSTER-AGENT     CLUSTER-CHECKS-RUNNER   AGE
datadog   Running (4/4/4)   Running (2/2/2)                           76d

❯ k get pdb -A | rg cluster

Describe what happened:
If the replica count is above 1, then PDB should be created according to this logic:

datadog-operator/controllers/datadogagent/poddisruptionbudget.go

Line 40 in 2b77d72

if dda.Spec.ClusterAgent.Replicas != nil && *dda.Spec.ClusterAgent.Replicas > 1 {

However, maybe because the apiVersion changed on the agent, it's not creating PDBs.

Describe what you expected:
PDB for cluster agent to be created

Steps to reproduce the issue:
Scale up replica of cluster agent to 2.

Hello,

Thanks for submitting the issue! You are right 0.8.x managed PDB for both Cluster Agent and Cluster Checks Runners, this isn't yet supported in 1.x.x, fact highlighted here. We haven't prioritized this for the upcoming 1.1.0, we may be able to do it for the next one.

Coming from the helm chart installation method, I noticed this was missing too.
