Summary

Currently, the COMPONENTS_LIMIT is hardcoded in the codebase. We can make this limit configurable to provide more flexibility for different GitLab installations.

Proposed Solution

Make the components limit configurable through either:

1. An environment variable (similar to GITLAB_CI_CONFIG_FETCH_TIMEOUT_SECONDS)
2. An application limit in the instance settings
