Deployment - improve on init_dela script

[PascalinDe]

currently the script is mainly for us to be able to quickly set up the environment, but it doesn't handle errors at all

• improve error handling
• see if it can be integrated into the initial setup

@PascalinDe do we still want this? Or can we close this issue?

this ticket can be closed as the script in question has been replaced in the meantime
