ScriptThrowsErrorInsideTransaction: subtle difference between "completed now" and "becomes completed momentarily"

After QUIT is totally random on timings, screw it.

Now uses ChannelMessageQueue.Completion.IsCompleted and should be consistent. Because _completion on UnboundedChannel respect no-synchronous-continuations, the old way doesn't behave as expected (IsCompleted isn't instantly set).

you know what? to hell with it: no connect logging *anywhere* unless you ask for it - it is *just noise*

* 新加scan,sentinels命令

* add command sentinels

transactions: don't log the connect crap; use a StringBuilder to buffer the tran log to avoid lots of sync blocks

Need to adjust simulated failure expectations here

Revert "show the result value in MessageFaulted, even if that means hydrating a RawResult to string"

This reverts commit d27aaa44.

This reverts commit 6ed17a99.

fix the thread-race around conditions/pending-work in RedisTransaction; this is *not* the problem we're looking for, it just needs fixing
