* INFRA-3988 | Ashvin | Add autoscaling to Flink
Autoscaling will only be supported by Flink versions 1.18 and later.
Migration is done using the following command
```shell
find . -name "manifest*flink*" | xargs -I{} sh -c "jq -r '.flink.flinkDeployment.flinkConfiguration += {\"autoscaler\": { \"enabled\": false }}' {} | sponge {}"
```
Adds validation in JSON schema
Updates kutegen with autoscaler changes
* INFRA-3988 | Ashvin | Remove promgateway configuration from Flink
This field is not required now that we use servicemonitor to fetch the
metrics. Earlier pushgateway was used.
Command used to do the migration is
```shell
find . -name "kub*flink*" | xargs -I {} sh -c "sed -i 's/promgate//' {}"
```
* INFRA-3988 | Ashvin | Add max-parallelism in test fixtures
Command used
```shell
find . -name "kube*flink*json" | xargs -I{} sh -c "jq -r '. | .kubeObject.items |= map(if .kind == \"FlinkDeployment\" then .spec.flinkConfiguration += { \"pipeline.max-parallelism\": \"100\" } else . end)' {} | sponge {}"
```
