As the title says, I updated the lint rules to no longer allow unwrap or
unimplemented.
Three special cases:
* Tests are allowed to use them
* std::sync::Mutex lock().unwrap() is common because it's usually
correct to continue panicking on poison
* `tokio::spawn_blocking(...).await.unwrap()` is common because it will
only error if the blocking fn panics, so continuing the panic is also
correct
I've introduced two extension traits to help with these last two, that
are a bit more explicit so they don't need an expect message every time.
## Problem
While reviewing #10152 I found it tricky to actually determine whether
the connection used `allow_self_signed_compute` or not.
I've tried to remove this setting in the past:
* https://github.com/neondatabase/neon/pull/7884
* https://github.com/neondatabase/neon/pull/7437
* https://github.com/neondatabase/cloud/pull/13702
But each time it seems it is used by e2e tests
## Summary of changes
The `node_info.allow_self_signed_computes` is always initialised to
false, and then sometimes inherits the proxy config value. There's no
need this needs to be in the node_info, so removing it and propagating
it via `TcpMechansim` is simpler.
Keeping the `mock` postgres cplane adaptor using "stock" tokio-postgres
allows us to remove a lot of dead weight from our actual postgres
connection logic.
## Problem
Any errors from these async blocks are unconditionally logged at error
level
even though we already handle such errors based on context.
## Summary of changes
* Log raw errors from creating and executing cplane requests at debug
level.
* Inline macro calls to retain the correct callsite.
## Problem
It is called context/ctx everywhere and the Monitoring suffix needlessly
confuses with proper monitoring code.
## Summary of changes
* Rename RequestMonitoring to RequestContext
* Rename RequestMonitoringInner to RequestContextInner
The overall idea of the PR is to rename a few types to make their
purpose more clear, reduce abstraction where not needed, and move types
to to more better suited modules.
