Add support for scheduling constraints on the chart

[mateusmuller]

Hello team,

The cronjob to collect data is quite cpu-consuming, usually it consumes a full cpu core. Due to that it impacts the workloads on the same node.

We'd like to schedule the job on specific nodegroups to avoid that, but looks like the chart doesn't support any customization. Would you please add support for:

• NodeAffinity
• NodeSelector
• Tolerations

Thanks!
