Document Drop behavior for Connection types

[DoumanAsh]

This is not per se feature, but rather documentatation issue.
Current documentation for Connection types is very limited to understand its behavior

https://docs.rs/hyper/1.0.0-rc.3/hyper/client/conn/http1/struct.Connection.html
https://docs.rs/hyper/1.0.0-rc.3/hyper/client/conn/http2/struct.Connection.html

It asks to poll it, but it doesn't say what will happen if you drop it (due to panic or other reasons)
It would be good to add more details on its behavior so that user could be confident in how to handle it after request had been handled

I don't see documentation for Drop behavior on Connection types. Could I try my hand at this issue?

Sure, always welcome!

[DoumanAsh]

@fercevik729 you should add documentation on Connection types directly rather than poll methods
This is where user would expect to see all details on how to use Connection

[fercevik729]

Sure thing!
