ib.feed: drop legacy "quote-with-vlm" polling 

Since now we explicitly check each mkt's venue hours now we don't need
this mega hacky "waiting on a quote with real vlm" stuff to determing
whether historical data should be loaded immediately. This approach also
had the added complexity that we needed to handle edge cases for tickers
(like xauusd.cmdty) which never have vlm.. so it's nice to be rid of it
all ;p
