[jasmin-30]

Issue

MASAIB-1670

Description

• This PR extends the MAS CLI aiservice-install command to support custom domain and DNS configuration, bringing it to feature parity with the main mas install pipeline for DNS-integrated deployments.

• AI Service standalone installation using mas aiservice-install supports:

  • Prompts to configure custom domain
  • Prompt to select DNS provider. (CIS & Route53 are supported at the moment)
  • Prompt to select Certificate issuer for selected DNS provider.
  • For CIS, prompt to configure enhanced security such as enabling WAF, proxy etc.
  • Non-interactive mode also support configuring domain and DNS provider.

• MAS & AI Service integrated installation using mas install:

  • Prompt to configure custom domain
  • When MAS is configured with Custom domain using DNS provider. CIS & Route53, AI Service inherits the same configuration.
  • DNS integration for AI Service is skipped when MAS DNS is configured with Cloudflare.
  • Interactive & Non-interactive mode now supports configuring enhanced security for CIS.
  • Non-interactive mode supports DNS configuration using Route53 which was available only for Interactive mode earlier.
