Implement resource requirement validation for plugins before installation

[mrgb7]

Problem

Currently, plugins are installed without checking if the cluster has sufficient resources (CPU, memory, disk) to run them. This can lead to:

• Failed deployments due to insufficient resources
• Resource contention and performance issues
• Unclear error messages when installations fail

Proposed Solution

Implement a resource requirement system that:

1. Define resource requirements per plugin

   • Add resource specifications to plugin metadata (CPU, memory, disk requirements)
   • Include minimum and recommended resource levels
   • Consider both control plane and worker node requirements

2. Pre-installation validation

   • Check cluster resource availability before plugin installation
   • Compare required resources against available cluster capacity
   • Provide clear warnings/errors if resources are insufficient

3. Implementation details

   • Add resource requirements to plugin configuration files
   • Create resource validation logic in the installer
   • Integrate with existing plugin installation workflow
   • Provide informative error messages with suggestions

Acceptance Criteria

• Plugin configurations include resource requirement specifications
• Installation process validates cluster resources before proceeding
• Clear error messages when resources are insufficient
• Optional --force flag to bypass validation if needed
• Documentation updated with resource requirements for each plugin

Benefits

• Prevents failed installations due to resource constraints
• Improves user experience with clear resource feedback
• Helps users make informed decisions about plugin installations
• Reduces troubleshooting time for resource-related issues
