Optionally ignore some plugin configuration fields

[danielpoonwj]

Hi,

We have a use case to optionally exclude certain fields in plugin configurations from deck dump/diff/sync. In our case, we have an external process that dynamically updates the acl plugin's allow list. We still want to be able to specify the acl plugin to manage the plugin association with a route but ignore any changes in config.allow.

Is this currently possible with any deck features? The expected behaviour would be similar to Terraform's lifecycle ignore_changes.

deck compares for the diffs in the entity state mentioned here: https://docs.konghq.com/deck/latest/reference/entities/.
