[Logic App] az logicapp create: Add the --domain-name-scope support

[jsharmaMSFT]

Related command
az logicapp create

Description
The change adds the support of --domain-name-scope parameter. The parameter helps customers to specify the domain name scope for the logic app. For example, when creating the logic app with --domain-name-scope SubscriptionReuse, it will create functionapp with the domain of the format of [appname]-[unique-string].[region].azurewebsites.net instead of the default domain of [appnames].azurewebsites.net.

Testing Guide
az logicapp create -g [resrouce-group] --subscription [azure-subscription] -p [appservice-plan] -n [logicapp-name] -s [storage-account-name] --domain-name-scope SubscriptionReuse

Pull request overview

Adds support for configuring the default hostname uniqueness scope when creating Logic Apps (az logicapp create), enabling “unique” hostnames (with a suffix) via --domain-name-scope.

Changes:

• Adds --domain-name-scope argument to az logicapp create and wires it through to the underlying Site model (autoGeneratedDomainNameLabelScope).
• Updates logicapp help with an example using the new flag.
• Adds an E2E test + recording validating the generated defaultHostName format when --domain-name-scope SubscriptionReuse is used.

For logicapp create, this argument is registered with a hard-coded choices=[...], but the module already imports AutoGeneratedDomainNameLabelScope (from azure.mgmt.web.models) and uses arg_type=get_enum_type(AutoGeneratedDomainNameLabelScope) for webapp create. Consider switching this to the enum-based arg_type as well to avoid duplicating allowed values and to keep behavior consistent with the other App Service commands (including any enum-driven parsing/validation improvements).

Suggested change

	c.argument('auto_generated_domain_name_label_scope', options_list=['--domain-name-scope'], help="Specify the scope of uniqueness for the default hostname during resource creation.", choices=['TenantReuse', 'SubscriptionReuse', 'ResourceGroupReuse', 'NoReuse'])
	c.argument('auto_generated_domain_name_label_scope', options_list=['--domain-name-scope'],
	help="Specify the scope of uniqueness for the default hostname during resource creation.",
	arg_type=get_enum_type(AutoGeneratedDomainNameLabelScope))
