**What this PR does / why we need it**:
<!-- Explain here the context and why you're making the change. What is
the problem you're trying to solve. --->

After using jobArgs.Endpoint data as the [reference
value](https://github.com/caraml-dev/merlin/blob/v0.34.0/api/queue/work/model_service_deployment.go#L61)
for the deployment, the CreatedUpdated value is set to the time default
value (`0001-01-01 00:00:00 +0000 UTC`) which could lead to DB update to
use this value. This PR fixes it by getting the created_at and
updated_at from version_endpoints DB so that it can be updated
correctly.
