Initializes a new instance ofClientBaseclass that
throwsNotImplementedExceptionupon invocation of any RPC.
This constructor is only provided to allow creation of test doubles
for client classes (e.g. mocking requires a parameterless constructor).
Creates a new client that sets host field for calls explicitly.
gRPC supports multiple "hosts" being served by a single server.
By default (if a client was not created by calling this method),
hostnullwith the meaning "use default host" is used.
