Add option to disabled PDB entirely within the helm chart or to set maxUnavailable manually

[cberge908]

Hi,

we're using Yugabyte in a DEV environment with one replica for master and tservers each.
Due to this setting the PDBs are automatically generated with a maxUnavailable setting of 0 for both statefulsets.
Unfortunately this blocks the automatic cluster node updates.

Would it be possible to either:

1. Add an option to the chart values to enabled/ disabled pod disruption budgets entirely

or

2. Set the values for the PDBs manually within the values file.

I do understand that this might not be wanted for most situations (where you would have at least 2 replicas for each) but it would be beneficial to have this option for scenarios like ours.

Cheers,
