public final class InstantiatingHttpJsonChannelProvider implements TransportChannelProviderInstantiatingHttpJsonChannelProvider is a TransportChannelProvider which constructs a ManagedHttpJsonChannel with a number of configured inputs every time getChannel(...) is called. These inputs include a port, a service address, and credentials.
The credentials can either be supplied directly (by providing a FixedCredentialsProvider to Builder.setCredentialsProvider()) or acquired implicitly from Application Default Credentials (by providing a GoogleCredentialsProvider to Builder.setCredentialsProvider()).
The client lib header and generator header values are used to form a value that goes into the http header of requests to the service.

getTransportChannel()
public HttpJsonTransportChannel getTransportChannel()Provides a Transport, which could either be a new instance for every call, or the same instance, depending on the implementation.
If #needsExecutor() is true, then #withExecutor(Executor) needs to be called first to provide an executor.
If #needsHeaders() is true, then #withHeaders(Map) needs to be called first to provide headers.
if #needsEndpoint() is true, then #withEndpoint(String) needs to be called first to provide an endpoint.
