Currently, sourcing lib.sh has side effects:

1. It tries to access multiple files (eg. config.toml) and fails if they
are not present
2. It creates a file in vault/container-name (which is not even needed
in production clusters)

That's not typical behaviour for a library and makes it hard to re-use.

This commit capsules all commands that read from certain files into the
new function load_conf_vars that is now run immediately after each
import of lib.sh where the variables are needed.

It also introduces a new function load_vault_container_name that is only
run when the container name is actually needed.
