TS-3020 Blind Tunnel fake request URL is IPv4 only.

> Key: TS-3020
> URL: https://issues.apache.org/jira/browse/TS-3020
> Project: Traffic Server
> Issue Type: Bug
> Affects Versions: 3.2.5
> Reporter: Patrick McGleenon
> Assignee: Leif Hedstrom
> Priority: Minor
> Fix For: 5.2.0
>
>
> HttpTransact::HandleBlindTunnel creates a fake request with HTTP version 0.9
> and CONNECT method. The URL for CONNECT used is created from destination IP
> and port - currently this is IPv4 only.
> requests with IPv6 destination IP addresses still work fine with the
> BlindTunnel since ATS is able to figure out the correct IPv6 destination from
> the Host Header of the fake URL. So this is a problem just in the ATS
> logging
> attached is a suggested patch for 3.2 - the latest version of the file hasn't
> changed much since then
> {code}
