enhancement: add ComputeClasses and VolumeClasses fields to BaseResources

[tylerslaton]

This commit enhances the BaseResources struct by adding ComputeClasses and VolumeClasses fields. These new fields allow for a more detailed specification of compute and storage resources, categorized by class instead of just by resource type.

This enhancement is crucial for accurately tracking the usage of memory, CPU, and storage for each specific compute or volume class. Consequently, the QuotaRequest logic has been updated to account for these new fields.

These new fields are maps and they introduce a unique approach to handle unlimited resources. They include special keys, AllComputeClasses and AllVolumeClasses. If a value is assigned to these keys in ComputeClassResources or VolumeClassResources, all compute or volume classes will be evaluated against the value.

Walkthrough

The recent update introduces a significant overhaul in how compute and volume storage resources are managed, shifting from individual resource quantities to structured ComputeClasses and VolumeClasses. This change affects resource tracking, allocation, and comparison across the system. Modifications include updates to resource addition, removal, fit checks, and string representation, alongside the introduction of new structures and methods tailored to handle the complexities of compute and volume class resources efficiently.

Tips

### Chat There are 3 ways to chat with CodeRabbit: - Review comments: Directly reply to a review comment made by CodeRabbit. Example: - `I pushed a fix in commit .` - `Generate unit-tests for this file.` - Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples: - `@coderabbitai generate unit tests for this file.` - `@coderabbitai modularize this function.` - PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples: - `@coderabbitai generate interesting stats about this repository from git and render them as a table.` - `@coderabbitai show all the console.log statements in this repository.` - `@coderabbitai read src/utils.ts and generate unit tests.` - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.` Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments. ### CodeRabbit Commands (invoked as PR comments) - `@coderabbitai pause` to pause the reviews on a PR. - `@coderabbitai resume` to resume the paused reviews. - `@coderabbitai review` to trigger a review. This is useful when automatic reviews are disabled for the repository. - `@coderabbitai resolve` resolve all the CodeRabbit review comments. - `@coderabbitai help` to get help. Additionally, you can add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. ### CodeRabbit Configration File (`.coderabbit.yaml`) - You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository. - The JSON schema for the configuration file is available [here](https://coderabbit.ai/integrations/coderabbit-overrides.v2.json). - If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: `# yaml-language-server: $schema=https://coderabbit.ai/integrations/coderabbit-overrides.v2.json` ### CodeRabbit Discord Community Join our [Discord Community](https://discord.com/invite/GsXnASn26c) to get help, request features, and share feedback.
