Deprecate getAzureResources and define resolveAzureResources to handle multi-path resource operations

[markcowl]

• Add a new public operation, resolveArmResources that returns new resource metadata

    export interface ResourceMetadata {
      /** The model type for the resource */
      type: Model;
      /** The kind of resource (extension | tracked | proxy | virtual) */
      kind: ArmResourceKind;
      /** The provider namespace */
      providerNamespace: string;
    }
  
    export interface ResolvedResource extends ResourceMetadata {
      /** The set of resolved operations for a resource.  For most 
          resources there will be 1 returned record */
      operations?: ResolvedOperations[];
    }
  
    export interface ResolvedOperations {
      /** The resource type (The actual respource type strign will be "${provider}/${types.join("/")}) */
      resourceType: ResourceType;
      /** The path to the instance of a resource */
      resourceInstancePath: string;
      /** The operations using this resourceInstancePath */
      operations: ArmResourceOperations;
    }
    
    export interface ResourceType {
      provider: string;
      types: string[];
    }
  
    export function resolveArmResources(program: Progam): ResolvedResource[];
    export function resolveArmResourceOperations(program: Progam, resourceType: Model): ResolvedOperations[];

• Deprecate getArmResources, resolveResourceOperations

• Relax constraints in @armResourceOperations to allow multiple sets of operations for a specific resource type

• Add test to verify correct generation of a multi-path resource

Implementation issue for #234 and in this gist
