The userId is used to identify the current user. It is automatically generated at the edge
when initializing the SDK for the first time.
Use this method when you want to identify the current user with an externally managed user ID.
For e.g., you can use this when an anonymous user logs in.
When an anonymous user logs in, you may also want to preserve all the user attributes tracked thus far.
The option preserveUserAttributes is available for the same, which merges all the attributes from
the current user.
The setUserId method also drops a cookie to track the user ID in browser environments. The cookie
is called cs-personalize-user-id.
Call this method before or after initializing the SDK.
