Add soft-delete feature

[justinyoo]

What are you trying to achieve?

Services like Azure Key Vault or Azure API Management has the soft-delete feature to avoid any accident from being deleted. I guess API Center should do the same because it behaves a central API repository of an organisation.

Proposed solution

• When deleting an APIC instance, it should be soft-deleted, then purged after.
• Through Azure Portal, there should be an option to disable soft-delete option. It should be enabled by default.
• Through Azure CLI, there should be an option to the create command like az apic service create --disable-soft-delete ...
• Through Azure CLI, there should be a command like az apic service purge ...

• Through bicep, there should be an attribute under the properties attribute like:

  resource apic 'Microsoft.ApiCenter/services@2024-03-01' = {
    name: 'apic-name'
    location: 'apic-location'
    properties: {
      disableSoftDelete: true|false
    }
  }

I found that we've introduced this soft-delete & purge feature from the API version of 2024-03-15-preview. Would it be possible to use the term "Purge" instead of "Delete" to keep following the convention with others like APIM and KeyVault?
