This pull request introduces significant updates to the buildchain and project configuration, including the removal of the ingress-nginx chart, the addition of support for the OLMv1 framework, and the integration of the nginx-operator. Key changes include the removal of old ingress-related charts, the addition of constants and tasks for OLMv1 and nginx-operator, and updates to image definitions. Below is a breakdown of the most important changes:

Removal of ingress-nginx Chart

• Removed the codegen_chart_ingress_nginx function and its associated tasks from buildchain/codegen.py.
• Deleted multiple YAML files related to ingress-nginx and ingress-nginx-control-plane charts under the charts/ directory. [1] [2] [3] [4] [5]

Addition of OLMv1 Framework

• Added a new codegen_olm function to generate SLS files for OLMv1 using a render script in buildchain/codegen.py.
• Introduced OLM_RENDER_SCRIPT and OLM_RENDER_CMD constants in buildchain/constants.py to support OLMv1 tasks. [1] [2]
• Added new paths for OLM-related files in the Salt tree (buildchain/salt_tree.py). [1] [2]

Integration of nginx-operator

• Added constants for nginx-operator paths and version in buildchain/constants.py and buildchain/versions.py. [1] [2]
• Defined new local images for nginx-operator and its bundle in buildchain/image.py.
• Added Salt states for deploying the nginx-operator in buildchain/salt_tree.py.

Updates to Image Definitions

• Updated the nginx-ingress-controller image to version v1.12.0 with a new digest.
• Added new images for OLM components (catalogd, operator-controller, opm) and the metalk8s-catalog-source. [1] [2]

Catalog Source for OLM

• Added a new catalog-source directory with a catalog.Dockerfile and related configuration files for the nginx-operator package. [1] [2] [3]

These changes collectively modernize the project by transitioning from the ingress-nginx chart to the nginx-operator and integrating the OLMv1 framework for enhanced operator lifecycle management.
