[RFE] Add support for OpenCost in KubePlus

[chiukapoor]

Description:

As KubePlus aims to provide a comprehensive solution for managing multi-instance multi-tenancy (MIMT) applications on Kubernetes, it would be beneficial to integrate support for OpenCost into the project.

Overview:

OpenCost is a cost management platform that provides insights and analytics into resource utilization and spending within Kubernetes clusters. By adding support for OpenCost into KubePlus, users will gain visibility into the resource consumption and associated costs of each application instance deployed using KubePlus.

Proposal:

Integration: Implement functionality within KubePlus to capture resource consumption data for each application instance. Data Export: Define an interface for exporting resource consumption data to OpenCost in a compatible format. Documentation: Update KubePlus documentation to include instructions on configuring and using the OpenCost integration. Testing: Conduct thorough testing to ensure the reliability and accuracy of the OpenCost integration.

Benefits:

Cost Visibility: Users will have clear insights into each application instance's resource usage and associated costs. Optimization: With visibility into resource consumption, users can optimize their deployments to minimize costs and maximize efficiency. Billing: Enables billing and chargeback mechanisms based on actual resource usage.
