test: check server warnings after each e2e test

[paula-stacho]

Description

Following mongodb-js/mongosh#2574

Added exceptions for warnings that we run into now. There is a global exceptions list, other exceptions can be added & removed at runtime.
I tried to keep them specific if possible, so that we'll see if something new is introduced.

Note: do hide whitespaces for review
