[Core feature] Add user id to security context

[ByronHsu]

Motivation: Why do you think this is important?

Currently, we do not have user id in the security context. Therefore, the developers are unable to decorate the task with user id on flytepropeller side.

Goal: What should the final outcome look like, ideally?

Add userid to security context protobuf and change related repo accordingly.

@MickJermsurawong will be collaborating on this issue. We will provide a configurable way to map securityContext.Identity to pod label.

Implementation:

1. Use taskCtx.TaskExecutionMetadata().GetSecurityContext() to extract securityContext from taskCtx (line)
2. Inject identity to objectMeta's label with customKey Name (line)

Config:

1. Developers should be able to config (maybe use configmap) which fields of securityContext.Identity to map to pod labels
