User Story

As a user
I want to run JS as a CLI parameter for mongosh
So that I can write bash scripts to automate MongoDB operations

Acceptance criteria

• Add support for running JS as a CLI parameter, with mongosh --eval "some script here"
• The script passed as parameter is executed and its result printed after mongosh exits
• If errors happen, mongosh exits with a non-zero error code and the error is printed
• .mongoshrc.js is executed after the script is evaluated if -shell is specified (-shell is added in MONGOSH-326.
