Ability to provide secret as argument value in run configuration

[bric3]

Similarly to #1 it might also be useful in some case to be able to have argument provider whose value is a secret that can be fetched in 1Password.

op item get "finnhub" --fields "token"

That said I understand that the IntelliJ SDK must provide a facility for such a feature.

That should work now with https://github.com/shyim/idea-1password/pull/11
