Interactive prompt appears when tty not attached

[smlx]

Describe the bug
Lagoon CLI always prompts interactively to create a config file even when it is not running in an interactive terminal.

To Reproduce
Steps to reproduce the behavior:

1. rm -f ~/.lagoon.yml
2. lagoon bash completion > /tmp/completion.sh
3. Command hangs

Expected behavior
Prompt should not appear unless the terminal is interactive. Also bash completion should not require a config file.
