+++   bug 1805267 +++
======================================================================

Description of problem:

imageio daemon and proxy do not support ipv6. We need to support setup when 
engine and hosts have only ipv6 address.

Known issues:
- daemon and proxy listen only to ipv4
- sending request to daemon using ipv6 url fails in requests library
- NBD ipv6 URLs are not supported in the daemon
- There are no tests using ipv6, so we don't know yet what needs to change

Comment 2 RHV bug bot 2020-06-22 11:12:54 UTC 
as per discussion with Nir, the behavior should be as follows:

Remote port - accessed by users
- Listen on "::" by default (like vdsm). Supports both ipv4 and ipv6
in the same time.
- Admin can override the address to ipv4 or ipv6 address. In this case
listen to the requested address
   (does not support both ipv6 and ipv4)
- Users should resolve host and connect to the first address that
works (like socket.create_connection())

Control socket - accessed only by engine
- Listen to the first interface resolved for "localhost". Can be ipv6
or ipv4 based on system configuration
- Client need to connect the first working address reported by
getaddrinfo() (like socket.create_connection())

Moving bug to 4.4. We need to clone to 4.3 if we really need to 
add this also in 4.3.

upload and download image on IPv4 and/or dual stack environment (to verify there's no regression) and same on IPv6-only environment to verify image upload/download works with IPv6 only.
