helm chart: JOB_KUBE_TOLERATIONS bad formatting

[ufou]

Environment

• Airbyte version: 0.36.1-alpha
• OS Version / Instance: k8s 1.20
• Deployment: Kubernetes deploy env
• Source Connector and version: n/a
• Destination Connector and version: n/a
• Severity: Low
• Step where error happened: Deploy

Current Behavior

If kube job tolerations are set via values the helm chart, the deployed ENV var for JOB_KUBE_TOLERATIONS will at best be malformed and at worst be invalid and cause jobs to fail

Expected Behavior

JOB_KUBE_TOLERATIONS to be valid and parsed as by the job to add the correct tolerations to the pod

Logs

n/a

Steps to Reproduce

1. I introduced this functionality in a previous PR but did not correctly identify that tolerations is an array of maps, rather than a map (like nodeSelector)

Are you willing to submit a PR?

Yes, incoming
