should we specify the behaviour expected if remove-existing-chain is set to be false yet willImportChain is true? warning & remove, or error out? or follow remove-existing-chainto not remove and continue with import?

Good point, maybe we should just error out. Otherwise we are somehow creating undefined behaviors?

@mb1896 What I would suggest is:
- if
remove-existing-chain, just remove the chain - if it's not specified, prompt the user with a y/n question asking whether they want the chain to be deleted -- if yes, do so, if not proceed without doing so

Thanks for including this! It needs to be moved up to the UNRELEASED section, though

(just a bit more clear, there isn't really a default since we're forcing users to specify)

You are right, however we couldn't differentiate between
- user not specifying a flag's value
- user specifically specifying a flag to false
That's why we have to ask for the user's input...

Probably want to handle case-sensitivity here

The ToLower() function handled it.
