Alias the host names in the redirector report

Alias the host names in the redirector report

The scheme is removed from the URL even for a custom report format and the
URL is always truncated to keep only the host name. The full URL was
always reported for a custom log format.

In addition, the reported host name is replaced by the alias if one is
defined.

There is no grouping of the identical host names as the report list one
access per line along with the access time so there is no grouping any
way.
