[FR] Auth: Provide an API to create/update users without unneeded API requests

[brettwillis]

The updateUser() and createUser() methods always perform two API requests under the hood: (1) the create/update request, and (2) a subsequent getUser() request.

In latency-sensitive applications where the result of getUser() is not required, this means an extra un-needed sequential round-trip network request. This fact is not apparent from the API or documentation.

Proposal

Add a second, optional parameter to createUser() and updateUser() called something like noFetchUserRecord which defaults to false (existing behaviour). If true, the getUser() request will be skipped, and the function will return Promise<void>, avoiding the un-needed round-trip request.

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

@lahirumaramba @prameshj I noticed you added the "help wanted" label. I'm more than happy to submit a PR for this, however we need to align on the proposal first. What are your thoughts?

@lahirumaramba @prameshj didn't get a response so assuming that you were ok with my original proposal? I have drafted the PR accordingly, along with tests etc, it would be great if you can take a moment to check it 🙏🏼 .
