Disable multi-line autocomplete based on a user setting

[makmic]

Hi :wave:

I noticed that the bug fix for https://github.com/makandra/geordi/issues/176 does not in fact disable multi-line autocompletion by default but only for a specific version constraint:

irb_version >= Gem::Version.new('1.2') && ruby_version < Gem::Version.new('3.0')

Personally I really dislike the autocompletion feature and would like geordi to never enable it for the geordi console <environment> command. To get there, I'd either have to modify the ~/.irbrc of every deployment and set IRB.conf[:USE_MULTILINE] = false (not feasible and probably not compatible with other dev's preferences).. or ask you to add a geordi setting :-)

Feature request

• Geordi exposes a new (project wide or global) setting for the .geordi.yml file
• E.g.

  use_multiline: false

• If the setting is false, geordi console should always use the -- --nomultiline flag

What do you think?
