Conrad Ludgate d1b60fa0b6 fix(proxy): delete prepared statements when discarding (#11165) 
Fixes https://github.com/neondatabase/serverless/issues/144

When tables have enums, we need to perform type queries for that data.
We cache these query statements for performance reasons. In Neon RLS, we
run "discard all" for security reasons, which discards all the
statements. When we need to type check again, the statements are no
longer valid.

This fixes it to discard the statements as well.

I've also added some new logs and error types to monitor this. Currently
we don't see the prepared statement errors in our logs.

chore(proxy): vendor a subset of rust-postgres (#9930)

README.md

This directory contains libraries that are specific for proxy.

Currently, it contains a signficant fork/refactoring of rust-postgres that no longer reflects the API of the original library. Since it was so significant, it made sense to upgrade it to it's own set of libraries.

Proxy needs unique access to the protocol, which explains why such heavy modifications were necessary.
