[profiles] Add event filter for watching dap

[khewonc]

What does this PR do?

Add an event filter to send DDA reconcile requests only when a DAP generation changes.

Motivation

Increased reconciles after adding DAP status since every DAP change was causing a DDA reconcile request.

Additional Notes

Anything else we should know when reviewing?

Minimum Agent Versions

Are there minimum versions of the Datadog Agent and/or Cluster Agent required?

• Agent: n/a
• Cluster Agent: n/a

Describe your test plan

Staging:

• Deploy the operator and check that the number of reconciles decreases

Other:

• Deploy an operator and spin up a DDA and profile
• Look at the number of reconciles. You can use the timestamp and Reconciling DatadogAgent log in the operator logs or the metric datadog.operator.controller_runtime_reconcile_total with controller:datadogagent. With default settings, it should be around 1 reconcile per 15 sec
• Edit the profile so that it won't change the generation (edit the status or add a label)
• Check that the profile generation remains the same (kubectl describe dap <profile>) and that the datadogagent reconcile count doesn't change per time period since the generation hasn't changed
• Edit the profile to change its generation (edit the profile spec)
• Check that the profile generation increases and that there's an extra datadogagent reconcile

Checklist

• PR has at least one valid label: bug, enhancement, refactoring, documentation, tooling, and/or dependencies
• PR has a milestone or the qa/skip-qa label
