Add Azure DB CRUD

[natereid72]

What problem are you facing?

Need to create a DB in and Azure DB instance. Using provider-sql fails because Crossplane is not running within the trusted network for Azure DB instance.

How could Crossplane help solve your problem?

Provider-azure could implement the CRUD APIs for Azure DB. This would eliminate the issue as the CRUD operations would be initiated at the Azure Cloud API instead of the Azure DB instance.
