Support for async delete methods in ResourceGroupsImpl

[amitarali]

Below way of implementation only support delete() method on ResourceGroup which is a blocking/sync call, beginDelete() or deleteAsync() methods are not supported. With the following approach of Azure client initialization, is there a way to use async delete methods which are part of class ResourceGroupsInner?

Azure azure = Azure.configure()
.withLogLevel(HttpLoggingInterceptor.Level.NONE)
.authenticate(appTokenCreds)
.withSubscription(subscriptionId);

azure.resourceGroups().delete(rgName);
