This adds a new (less severe) blacklist reason as well as an option to configure the timeout. This blacklist reason will be used in cases where a BSS has requested IWD roam elsewhere. At that time a new blacklist entry will be added which will be used along with some other criteria to determine if IWD should connect/roam to that BSS again. Now that we have multiple blacklist reasons there may be situations where a blacklist entry already exists but with a different reason. This is going to be handled by the reason severity. Since we have just two reasons we will treat a connection failure as most severe and a roam requested as less severe. This leaves us with two possible situations: 1. BSS is roam blacklisted, then gets connection blacklisted: The reason will be "promoted" to connection blacklisted. 2. BSS is connection blacklisted, then gets roam blacklisted: The blacklist request will be ignored
