WiP: diagnostic setting: metrics and logs to LogAnalytics

[zioproto]

Azure OpenAI has diagnostic settings that make possible to send logs and metrics to a destination.

The possible destinations are:

• Log Analytics workspace
• Storage account
• Event Hub
• partner solutions

This is how the config looks in the portal:

I am not sure if the right approach is to have the azurerm_monitor_diagnostic_setting resource inside or outside this module.

• Inside: the logic is quite complex because of the activation of individual logs and metrics in combination to the activation of possibly multiple destinations. Moreover there could be multiple diagnostic setting resources. See how many "NOTE:" section the azurerm_monitor_diagnostic_setting resource has.
  We could decide to support only a subset of the possible configurations.
• Outside: requires a new output for azurerm_cognitive_account.this.id and we leave to the user the task of managing the complexity.

I am looking for feedback on how to move forward. Thanks
