copilot-cli: Release v1.9.0

⚡️ Features and enhancements

• Introduce custom domain names for App Runner workloads (#2664)

  We now support the alias field in Request-Driven Web Service manifests, too!
  You can specify a friendly URL instead of the default App Runner-generated endpoint.

• Allow multiple environments per VPC (#2515)

  You can now import the same VPC multiple times when running env init.
  This change does not disrupt existing environments.

• Enable building images with ARM hosts (#2636)

  If you're on ARM architecture, your images will automatically target the linux/amd64 platform at build time.
  A new manifest field, platform, shows the value to be passed with the --platform flag.

• Implement the grace_period and deregistration_delay manifest fields (#2576)

  You may now customize these attributes in your Load Balanced Web Service manifest.

  http:
    healthcheck:
      grace_period: 30s    # How long to ignore unhealthy healthchecks after a deployment. 
    deregistration_delay: 45s   # How long to wait before deregistering the tasks.

• Add the credential parameter for private repositories (#2582)

  Store the credentials to your private repo using AWS Secrets Manager, then pass them into your container definition using this new manifest field.

• Support entrypoint and command overrides for sidecars (#2592)

  Override the default values for these config fields in your manifest--not just for your main container, but now for your sidecars, too.

• Enable fish completion (#2517)

  Install completion for your fish shell with copilot completion fish.
