backport knative#1800
This makes io: read/write on closed pipe go away.

* fix: bad connection handling for in cluster dialer

Connections were closed from wrong end of io.Pipe
which resulted in confusing error logs.

Signed-off-by: Matej Vasek <[email protected]>

* feat: DialContext() better error handling

Now DialContext() returns some errors immediately
instead of deferring it Read/Write operation on the returned connection.

* feat: DialContext() more better error handling

Now ContextDial() tries to parse socat's stderr and translate it to Go's net.OpError
instead of just creating error with whole stderr embedded in it.
