Expose more remote functions options as first class properties

[jialuoo]

Similar to #1552

To better access the hidden properties in remote function, it would be nice to have following options exposed via first class properties:

• "maxBatchingRows"
• "containerCpu"
• "containerMemory"

Are these three items really available as attributes of RemoteFunctionOptions? I only see maxBatchingRows, I don't see containerCpu or containerMemory in the REST Reference docs under remoteFunctionOptions (I see the same lack in our Google-internal proto docs).
https://cloud.google.com/bigquery/docs/reference/rest/v2/routines#remotefunctionoptions

{
 "endpoint": string,
 "connection": string,
 "userDefinedContext": {
 string: string,
 ...
 },
 "maxBatchingRows": string
}

Or did we mean that they should be exposed simply as external runtime options.
I do see them as listed as attributes associated with ExternalRuntimeOptions in both the REST reference docs and Google-internal protos.
https://cloud.google.com/bigquery/docs/reference/rest/v2/routines#externalruntimeoptions

{
 "containerMemory": string,
 "containerCpu": number,
 "runtimeConnection": string,
 "maxBatchingRows": string,
 "runtimeVersion": string
}

So, is the ask to provide these items as attributes associated with first class attributes of a routine's external runtime options?

Yes
