Need more detail in instructions

[mattbriggs]

@ewebster-neal I am trying to follow the instructions in running the FHIR Server on K8 on Azure Stack Hub.

In particular, I need more information on how to establish the credentials and the meaning of some of the instructions in the Environmental Definition parameters:

• FHIR_VERSION: this is clear.
• FHIRServer__Security__Authentication__Audience: I am not sure how to specify the audience. The service doesn't contain an audience value. Is this the application ID, object ID, or other value?
• FHIRServer__Security__Authentication__Authority: This value is also obscure. Is this the secret/key for the SPN?
• SAPASSWORD: How do I specify the SQL DB connection string? Is this the connection string?
• ApplicationInsights__InstrumentationKey: Is this required?

In addition, can you point me to recommended instructions or how I might get the cert for Kestrel?
