Parse default Azure error format and extract message, error code and additional properties

[pakrym]

We should also consider extracting inner errors.

Spec:

https://github.com/microsoft/api-guidelines/blob/vNext/Guidelines.md#7102-error-condition-responses

Remove existing implementations:

https://github.com/Azure/azure-sdk-for-net/blob/master/sdk/keyvault/Azure.Security.KeyVault.Shared/src/ClientDiagnostics.cs
https://github.com/Azure/azure-sdk-for-net/blob/master/sdk/formrecognizer/Azure.AI.FormRecognizer/src/ClientDiagnostics.cs
​https://github.com/Azure/azure-sdk-for-net/blob/master/sdk/textanalytics/Azure.AI.TextAnalytics/src/ClientDiagnostics.cs

With this work item, we can have opportunities for full support for ARM exceptions without having to create a separate ArmException. This will help create consistent result from data plane and mgmt plane code. The ARM exception pretty much fit the error response laid out in the spec above.

We looked at ArmException class and the mapping of the fields into a standard Exception:

• Suggested Mapping. Please note. Details are deserialized into Exception trees and set on InnnerException via a AggregatedException.

Exception Class	RequestFailedException	ArmException	REST ARM ErrorResponse
Message			Message
Source		Target	Target
InnerException		Details	Details
Data		Store in data dictionary and expose via AdditionaInfo (Client_ReqId, ReqId Request, Response ?) Any additional custom exception data	AdditionalInfo
StackTrace
...	Status (http)
	Code		Code

• Allow user access to response headers for things like CorrelationId, ClientRequest-Id etc. While having few special ones as first class properties, we are ok with access via a ResponseHeader property.
