attributes for admission control enforcement

[srcporter]

Changes to the default ACS admission control configuration:

• Enable listening (and enforcement) of policy on Deployment create, update, and edit verbs
• Lower the admission control timeout to 10 seconds to ensure that ACS doesn't cause Kube API timeouts
• Allow ACS to evaluate image contents (vulnerabilities) in Admission Control (fails open after timeoutSeconds)
• Change the collection method to CORE_BPF which will be the default method in ACS 4.4 and later
