Feature Request: integrate kube-ps1 as OMB plugin

[rafacouto]

Description

I recently installed oh-my-bash and it's working great, but I'm unable to get kube-ps1 integration working properly. kube-ps1 is a very popular and useful plugin for Kubernetes users that displays the current Kubernetes context and namespace in the bash prompt.

Current Situation

• kube-ps1 is not included as an oh-my-bash
• Manual installation requires cloning the repository and custom configuration
• The integration with oh-my-bash's theme system is not straightforward
• Other popular shell frameworks like oh-my-zsh already include kube-ps1 as a plugin.

Proposed Solution

Add kube-ps1 as an plugin in oh-my-bash with:

• Proper plugin initialization
• Theme integration support
• Standardized configuration options
• Documentation

Why this is valuable

• Kubernetes is widely used in development and DevOps
• kube-ps1 has over 2.8k stars on GitHub indicating high demand
• Would provide a consistent experience for Kubernetes users
• Aligns with oh-my-bash's goal of providing useful plugins

Technical considerations

The plugin should:

• Follow existing plugin structure
• Integrate with the prompt system
• Respect existing oh-my-bash configuration
• Provide toggle enable/disable functionality

Contributions are welcome. One may consider porting the corresponding Oh-My-Zsh plugin.

I should note one thing: the original kube-ps1 seems to be licensed under Apache 2.0 License, which is incompatible with the MIT license that Oh My Bash uses, so a special care is needed if any codes from the upstream kube-ps1 would be imported into Oh My Bash.
