[Bug] fix RayActorOptionSpec.items.spec.serveConfig.deployments.rayActorOptions.memory int32 data type

[kevin85421]

Why are these changes needed?

Based on actor.py, the unit of memory is specified as "byte". However, the data type of Memory in RayActorOptionSpec is specified as int32. The maximum value of int32 is 2^31 - 1. Therefore, if a user specifies a value larger than 2GB (2^31 bytes), it will result in an overflow. Hence, this PR updates the data type to uint64 instead.

• proto/: I only updated serve.proto, and the other changes were generated by make generate.

• CRD ray.io_rayservices.yaml: This is entirely maintained by the code generator. It's worth noting that YAML does not support unsigned integers [1], so in the CRD, the type is int64 instead of uint64.

  • [1] I cannot find the statement in the official YAML documentation, but there are multiple sources indicating that this is indeed true.
