import-export: Improve timeout error reporting

When the source cluster takes too long to create a snapshot, the
destination would time out. Unfortunately no good error message was
written unless debug logging was enabled, not even to the log file. This
will be improved with this patch....

Support for resolving hostnames to IPv6 addresses

This patch enables IPv6 name resolution by using socket.getaddrinfo
instead of socket.gethostbyname_ex.

It renames the HostInfo class to Hostname and unifies its use throughout
the code. This is achieved by using static calls where no object is...

import/export daemon: Add support for a magic prefix

This “magic” value will be used to ensure that we don't accidentially
connect to the wrong daemon (e.g. due to a bug), comparable to DRBD's
per-disk secret. Just depending on the SSL certificate isn't enough...
