Add VenafiConnection CRD to discovery-agent Helm chart

[inteon]

This pull request introduces new configuration options and resources to improve the management and deployment flexibility of the Venafi Connection within the Discovery Agent Helm chart. The main changes allow users to optionally include or exclude VenafiConnection CRDs and RBAC, specify the namespace for the Venafi service account, and ensure proper RBAC and CRD templating. Additionally, the Helm chart documentation, schema, and Makefile targets are updated to support these enhancements.

Venafi Connection configuration and templating:

• Added venafiConnection configuration block to values.yaml and its schema, allowing users to control inclusion of VenafiConnection CRDs/RBAC and specify the service account namespace. [1] [2] [3] [4]
• Updated Helm templates to conditionally render VenafiConnection CRDs and RBAC based on the new config, and to use the specified service account namespace. [1] [2] [3]
• Added templating helpers for VenafiConnection labels and chart naming.

CRD and Makefile updates:

• Added conditional headers for CRD generation to support Kubernetes version differences and the new include logic. [1] [2] [3]
• Updated Makefile logic to support new CRD generation and verification targets, ensuring proper sequencing and compatibility with the new Helm chart structure. [1] [2] [3] [4] [5] [6]

Documentation and dependency updates:

• Expanded README.md to document the new Venafi Connection configuration options.
