Allow auto-approve only for tagged resources

Is your feature request related to a problem? Please describe.
Auto approval is binary right now, all or nothing. It would be ideal to allow auto-approve only for certain resources.

Describe the solution you'd like
Allow auto approve for tagged resources. Ideally, if the resource has a tag (e.g. auto-approve), no matter which value, it should be a candidate for auto approvals. In case the resources doesn't have the configured tag, the system should follow the default flow.

Additional context
When auto-approve-all is enabled, this option should be ignored and just auto-approve everything.
