Centralise default config values

In a lot of commands, we retrieve config values as follows:

cli.getSettingWithDefaultValue<boolean>(settingsNames.autoOpenLinksInBrowser, false)

I don't think it's a good approach to define the default value in the command itself. A better approach would be that we centralize all default values and provide a new function where the user should only specify the config variable. E.g.:

cli.getSetting<boolean>(settingsNames.autoOpenLinksInBrowser)
