[API] Use a common dependency in model monitoring endpoints

[jond01]

A mini-PR related to ML-5865 to allow neat code reuse.

Aggregate the following in common params:

• project
• auth_info (sub-dep)
• db_session (sub-dep)

For reference, see:

https://fastapi.tiangolo.com/tutorial/dependencies/sub-dependencies/

I verified that enable_model_monitoring works.

Cool use of that common dependency approach for the APIs :)
As a future optimization, I suggest that we will modify the _common_parameters func and use it across other MLRun APIs.
