Option to set CPU always allocated in functions v2

I would like to set "CPU always allocated" to my cloud functions with min instances set so that they will maintain their connection to spanner. Currently the connection is being killed when the function has no CPU because there are no requests processing. It would be great to have this as an option when deploying functions.

See this link for this suggesiton from the spanner team: https://github.com/googleapis/nodejs-spanner/issues/1682#issuecomment-1228099611
