Configure NIC pods with zone_sync enabled with TLS support

[AlexFenlon]

Is your feature request related to a problem? Please describe.
As an engineer, I want zone_sync to have TLS as a feature for NIC to allow state sharing.
Prereq: #7219

nginx directives needed for this issue

zone_sync_ssl
zone_sync_ssl_certificate
zone_sync_ssl_certificate_key
zone_sync_ssl_trusted_certificate
zone_sync_ssl_crl
zone_sync_ssl_verify

Acceptance Criteria

• Include TLS for this issue
• zone-sync data read from the nginx-config (ConfigMap) including zone-sync TLS values: ssl secret, trusted cert and verify them
• input data validated (including security validation - see above)
• generate headless service with TLS (no user input, read namespace name only)
• templates generate correct zone-sync config with TLS
• Helm implementation for TLS
• Manifest implementation for TLS
