fix: prefix telemetry endpoint with 'management.'

[gahyusuh]

What was the problem/requirement? (What/Why)

From the client submitter, we used to send client telemetry requests (code here) to the service endpoint. I found that request.urlopen(req) is failing with below error.

<urlopen error [Errno -2] Name or service not known>

What was the solution? (How)

The endpoint that we were using was incorrect. It should be prefixed with management..

What is the impact of this change?

We can now send the client telemetry requests.

How was this change tested?

• Ran unit tests and made sure all tests passed.
• Manually tested by submitting jobs using the CLI against Alpha, Beta, and Prod endpoints. Confirmed that the client telemetry events were correctly recorded for each of those stage.

Was this change documented?

No.

Is this a breaking change?

No.
