Description

When bash is configured with errexit, it kills the session even when you are trying to quit a program which is very annoying.

1. Run make api-development
2. Start a bash session dco -p lagoon exec api-db bash
3. Run a command, eg less /etc/mysql/my.cnf
4. Press ctrl + c
5. The bash session is killed, not just less

This happens because the set -eo pipefail in an entrypoint is sourced in .bashrc which sets errexit for the entire session.

Other entrypoints can set -e but they are executed instead of sourced, so they don't pollute the bash session.
