fix: fold timeout into scope query

[ferhatelmas]

What kind of change does this PR introduce?

Refactor for perf

What is the current behavior?

Right now, statement timeout is sent separately which introduces extra round trip.

What is the new behavior?

Delay until the first statement (set_config) and combine them together in the same query to reduce one round trip to db.

Additional context

Additionally, make query text for scope module level, and cache headers/jwt payload for multiple queries in the same connection.

It's an interesting approach, but it might beat us in case we never call setScope on a query, and expect the timeout to still work.

Not sure if it's worth the performance gain here (1ms or less) vs a bit of a hidden timeout logic
