refactor: Replace yaml manifests with k8s resources and map implicit dependencies

[bryantbiggs]

What does this PR do?

• Replaces yaml manifest for EKS ADOT plugin with K8s resources - removes need to add kubectl provider to obsv. examples
• Map implicit dependencies to aid in deployment ordering (cert_manager -> opentelemetry-operator / eks-adot -> collector)
• Add terraform-aws-managed-service-prometheus; this provisions the AMG workspace but also provides the workspace IAM role for single account usage, workspace SAML configuration, license assocaition, and role association. Once r/grafana_workspace_api_key hashicorp/terraform-provider-aws#25100 is resolved, the extra step of manually fetching API keys will be resolved and handled by code, and aws_grafana_role_association fails to associate AWS SSO user/group IDs hashicorp/terraform-provider-aws#24166 will resolve user management via code as well. This reduces the steps required by users to streamline the provisioning of the example
• Replace blueprints implementation of prometheus module with terraform-aws-managed-service-prometheus which implements the workspace as well as the alert manager definition and rule group namespaces
• Refactor opentelemetry-operator to add support for current self-managed addon route while also supporting the new EKS ADOT addon
• Refactor adot-collector-* addons to flatten configuration to main.tf

⚠️ Note - this is a PR into @bonclay7 's existing PR, not into main

Motivation

• Improve blueprint usability
• Ensure support for both self-managed opentelemetry-operator and EKS ADOT addon
• Better inter-dependency management between addons
