Gets the ExecutorProvider that was previously set on this Builder. This ExecutorProvider is
to use for running asynchronous API call logic (such as retries and long-running operations).
This ExecutorProvider is not used to set the executor in TransportChannelProvider.
Deprecated.Please use #getBackgroundExecutorProvider() for getting the executor
provider that's used for running scheduled API call logic.
Gets the ExecutorProvider that was previously set on this Builder. This ExecutorProvider is
to use for running asynchronous API call logic (such as retries and long-running operations),
and also to pass to the transport settings if an executor is needed for the transport and it
doesn't have its own executor provider.

Sets the HeaderProvider for getting custom static headers for http requests. The header
provider will be called during client construction only once. The headers returned by the
provider will be cached and supplied as is for each request issued by the constructed client.
Some reserved headers can be overridden (e.g. Content-Type) or merged with the default value
(e.g. User-Agent) by the underlying transport layer.
Sets the HeaderProvider for getting internal (library-defined) static headers for http
requests. The header provider will be called during client construction only once. The
headers returned by the provider will be cached and supplied as is for each request issued by
the constructed client. Some reserved headers can be overridden (e.g. Content-Type) or merged
with the default value (e.g. User-Agent) by the underlying transport layer.
