Issue:
Implement basic support for Otel
### Overview
**As a** site reliability engineer who wants to monitor my traffic traces,
**I want to** configure NGINX Ingress Controller to send traffic traces to my provider of choice
**so that** I can have a clear picture of how my system's traffic is behaving

### Acceptance Criteria
- [x] Allow tracing to be configured through native NGINX Otel library
- [ ] Ensure documentation provides an example of at least one trace provider (e.g. Data Dog or Grafana)

### Documentation
NGINX Otel module: https://nginx.org/en/docs/ngx_otel_module.html
Otel vendors: https://opentelemetry.io/ecosystem/vendors/

### Example Config Map 
Add equivalent support for OpenTelemetry as was deprecated for OpenTracing with a similar UX.

```
apiVersion: v1
kind: ConfigMap
metadata:
  name: nginx-config
data:
  otel-exporter-endpoint: "[(http|https)://]host:port" # Required
  otel-exporter-trusted-certificate-secret: # Optional nginx.org/ca Secret name 
  otel-exporter-header-name: "name" # Optional
  otel-exporter-header-value: "value" # Optional
  otel-service-name: "unknown_service:nginx" # Optional
  otel-global-trace-enabled: "false" # Optional, enables otel tracing at the http context
```

Support at the Server/Location level will be via snippet on VS/VSR/Ingress


- [x] Add validation for missing either header name or value
- [x] Add validation for other field present without the required otel endpoint
- [ ] update trusted cert on secret or secret name update
- [x] Add unit tests
- [x] Add python tests to verify generated nginx config


Discussion:
@pdabelf5: the `nginx-module-otel` package is not available for `arm`, `s390x` & `ppc64le` architectures.  These have been removed from the build pipelines to allow testing to complete.@pdabelf5: The `nginx-module-otel` & `nginx-plus-module-otel` rpm packages depend on the `c-ares` shared library.  The full RHEL distributions include this libarary package, whereas, `ubi8` & `ubi9` do not include the `c-ares` package in the base package repository.

+# Learn how to use OpenTelemetry with F5 NGINX Ingress Controller
+
+NGINX Ingress Controller supports [OpenTelemetry](https://opentelemetry.io/) with the NGINX module [ngx_otel_module](https://nginx.org/en/docs/ngx_otel_module.html).
+
+## Prerequisites
+
+1. Use a NGINX Ingress Controller image that contains OpenTelemetry.
+
+    - All NGINX Ingress Controller v5.1 images or later will contain support for `ngx_otel_module`.
+    - Alternatively, you follow [Build NGINX Ingress Controller](https://docs.nginx.com/nginx-ingress-controller/installation/build-nginx-ingress-controller/) using `debian-image` (or `alpine-image` or `ubi-image`) for NGINX or `debian-image-plus` (or `alpine-image-plus`or `ubi-image-plus`) for NGINX Plus.
+
+1. Enable snippets annotations by setting the [`enable-snippets`](https://docs.nginx.com/nginx-ingress-controller/configuration/global-configuration/command-line-arguments/#-enable-snippets) command-line argument to true.
+
+1. Load the OpenTelemetry module.
+
+    You need to load the module using the following ConfigMap key:
+
+    - `otel-exporter-endpoint`: sets the endpoint to export your OpenTelemetry traces to.
+
+    The following example shows how to use this to export data to an OpenTelemetry collector running in your cluster:
+
+    ```yaml
+    otel-exporter-endpoint: "http://otel-collector.default.svc.cluster.local:4317"
+    ```
+
+## Enable OpenTelemetry globally
+
+To enable OpenTelemetry globally (for all Ingress, VirtualServer and VirtualServerRoute resources), set the `otel-trace-in-http` ConfigMap key to `true`:
+
+```yaml
+otel-trace-in-http: "true"
+```
+
+## Enable or disable OpenTelemetry per Ingress resource
+
+You can use annotations to enable or disable OpenTelemetry for a specific Ingress resource. As mentioned in the prerequisites section, `otel-exporter-endpoint` must be configured.
+
+Consider the following two cases:
+
+### OpenTelemetry is globally disabled
+
+1. To enable OpenTelemetry for a specific Ingress resource, use the server snippet annotation:
+
+    ```yaml
+    nginx.org/server-snippets: |
+        otel_trace on;
+    ```
+
+1. To enable OpenTelemetry for specific paths:
+
+    - You need to use [Mergeable Ingress resources](https://docs.nginx.com/nginx-ingress-controller/configuration/ingress-resources/cross-namespace-configuration)
+    - You need to use the location snippets annotation to enable OpenTelemetry for the paths of a specific Minion Ingress resource:
+
+        ```yaml
+        nginx.org/location-snippets: |
+            otel_trace on;
+        ```
+
+### OpenTelemetry is globally enabled
+
+1. To disable OpenTelemetry for a specific Ingress resource, use the server snippet annotation:
+
+    ```yaml
+    nginx.org/server-snippets: |
+        otel_trace off;
+    ```
+
+1. To disable OpenTelemetry for specific paths:
+
+    - You need to use [Mergeable Ingress resources](https://docs.nginx.com/nginx-ingress-controller/configuration/ingress-resources/cross-namespace-configuration)
+    - You need to use the location snippets annotation to disable OpenTelemetry for the paths of a specific Minion Ingress resource:
+
+        ```yaml
+        nginx.org/location-snippets: |
+            otel_trace off;
+        ```
+
+## Customize OpenTelemetry
+
+You can customize OpenTelemetry through the supported [OpenTelemetry module directives](https://nginx.org/en/docs/ngx_otel_module.html). Use the `location-snippets` ConfigMap keys or annotations to insert those directives into the generated NGINX configuration.
+
+> Note: At present, the additional directives in the `otel_exporter` block cannot be modified with snippets.
