fix: quota validation error fixed

[Priyanka-Microsoft]

Purpose

• ...
  This pull request introduces significant enhancements to the quota validation scripts (validate_model_quota.ps1 and validate_model_quota.sh) for better usability, error handling, and user guidance. Key changes include improved messaging, input validation, fallback region handling, and a more robust flow for manual user input.

Improvements to user messaging and feedback:

• Enhanced error and warning messages in validate_model_quota.ps1 and validate_model_quota.sh to provide clearer context, such as displaying available and required quotas ($PrimaryResult.Available, $Capacity) and recommended regions when capacity is below the threshold. [1] [2]

Enhanced fallback region handling:

• Introduced a check_fallback_regions function in validate_model_quota.sh to streamline the process of identifying and suggesting fallback regions with sufficient quota. This function also displays a table of fallback regions and their quota details. [1] [2]

Improved input validation and user guidance:

• Added checks for minimum recommended capacity (e.g., RECOMMENDED_TOKENS=200) in both scripts, warning users about potential performance issues if the entered capacity is too low, and prompting for confirmation to proceed. [1] [2]
• Reorganized input validation logic in validate_model_quota.sh to ensure all required parameters are provided and valid before proceeding.

Refactoring and code organization:

• Consolidated redundant logic in validate_model_quota.sh by introducing helper functions like show_table and manual_region_input for better modularity and readability. [1] [2]
• Removed unused or redundant code blocks, such as outdated input validation and fallback handling logic, to simplify the scripts.

Additional minor updates:

• Updated comments and formatting for better clarity and consistency across both scripts. [1] [2]
