sslutil: check for ui.insecureconnections in sslkwargs The end result of this function is the same. We now have a more explicit return branch. We still keep the old code looking at web.cacerts=! a few lines below because we're still setting web.cacerts=! and need to react to the variable. This will be removed in an upcoming patch.

dispatch: set ui.insecureconnections when --insecure is used

ui: add an instance flag to hold --insecure bit Currently, when --insecure is used we set web.cacerts=! and socket validation takes this value into account. web.cacerts=! is not documented AFAICT and is purely an internal implementation detail. Let's be more explicit about what is going on by introducing a dedicated variable outside of the config values to track that --insecure is used.
