fix: Add Missing Flags as Helm Values

[ianstanton]

trafficstars

What this PR does / why we need it: Add the following flags as helm values and pass down to controller-manager and audit deployment templates:

• --log-level-key
• --log-level-encoder
• --cert-dir
• --api-cache-dir
• --otlp-endpoint
• --otlp-metric-interval
• --stackdriver-only-when-available
• --stackdriver-metric-interval
• --disable-enforcementaction-validation
• --client-ca-name
• --client-cn-name

Which issue(s) this PR fixes (optional, using fixes #<issue number>(, fixes #<issue_number>, ...) format, will close the issue(s) when the PR gets merged): Fixes #3784

Special notes for your reviewer: I left some of the missing flags in #3784 out as I'm still determining whether they belong as chart values. I also want to be sure the right flags are passed to the appropriate deployments (some are applied to both, others are unique to controller-manager or audit), so feedback is welcome there.
