HTTP check should set User-Agent to something custom

[jsternberg]

Inside of our Nginx logs I'll see something like this:

127.0.0.1 - - [22/Jun/2015:21:42:31 +0000] "GET / HTTP/1.1" 200 668 "-" "Go 1.1 package http"

I'm also running a Go program on this same computer and I thought the program was acting erroneously. It turns out this is just from Consul checking the HTTP endpoint. I'd like it if Consul set a custom User-Agent so I can see "Yep, this is Consul checking the HTTP health".

Thanks.

Makes sense, tagged as an enhancement!

It looks like this was already resolved in #951 via commit ce93fdd which should be in 0.5.2.

Ah, yep! Closing this out.
