local socket binding for TCPConnector

[akhomchenko]

As discussed here:

https://groups.google.com/forum/#!topic/aio-libs/lM7IUZq3DNM

Please list tests that should be written.

[asvetlov]

Don't use markup here but update ./docs/client_reference.rst also.
(local_addr, local_port) should be (local_host, local_port) pair.

[asvetlov]

I suggest the following test scenario:

1. Select unused port on loopback (127.0.0.1) interface.
2. Make http request with passing selected local_addr
3. Check that socket from connector._conns transport has local_addr as sock.gethostname()

[asvetlov]

Is it possible to use (0.0.0.0, 1234) and (127.0.0.1, 0) pairs for local_addr?

@asvetlov

As for:

(0.0.0.0, 1234)

0.0.0.0 was resolved to 127.0.0.1 in my case

(127.0.0.1, 0)

0 port is translated to first free port, so it would not be (127.0.0.1, 0)

@asvetlov looks like builds for Python 3.5 are broken

[asvetlov]

Thanks!
