Go-ipfs: ipfs suspend && ipfs continue

[JayBrown]

I sometimes need to interrupt/suspend the ipfs daemon, and later continue it; currently I'm doing it with kill -TSTP <ipfs-pid> and kill -CONT <ipfs-pid>. Since we already have ipfs shutdown, it would be great to have ipfs suspend and ipfs continue too.

I don't know any where we could internally suspend whole daemon, the STP signal works externally on the scheduler.

@JayBrown would a command for putting the daemon in and out of offline mode work for you?

[JayBrown]

Nice, thank you. That should work, I believe.

@JayBrown cool, thats on our todo list. I'll bump it onto the 0.4.12 milestone so it gets attention sooner.
