Samples are out of date and existing documentation and templates are invalid

[bl00mie]

The sample implementations are out of date.

• AddAzureTableStores<ApplicationDbContext> does not exist for a single Func parameter. IdentityAzureTableBuilderExtensions has 2 AddAzureTableStores extension methods, but both require a Func<IdentityConfiguration> and a Func<TableServiceClient>
• As noted in the v9.0 release docs, the AzureTable.Model.IdentityConfiguration does not contain a StorageConnectionString field. It seems simple enough to have a TableServiceClient available for injection, but the code samples and templates have this as an error.
• CreateAzureTablesIfNotExists<TContext> extention method won't accept ApplicationDbContext as the context type.
