This moves to our normal directory layout, and removes the unused ConnectionWatcher.

Note 1: There's an apparently unused StackExchange.Redis.Modules I'm not sure about....going to let Marc nuke it if sure.

Note 2: the sentinel redis configs which are usually redis ignored may have absolute paths in them that need a quick update to get going again in a killall-> change config -> ./start-all.sh

cc @mgravell on above ^

Note: this doesn't include command and key, which is still behind the IncludeDetailInExceptions flag

I HATE this, but it's now just plain broken, and no one's going to fix it (or accept a fix for it).

Some socket fixes are in here...let's make sure we're getting them.

We're getting an extra in prod...need to figure out what it is. I'm betting a heartbeat in there.
