Bulk create hosts

Adds one or more hosts to the account. No errors will be reported if the list includes one or more hosts that already exist. In that situation, the existing hosts will be treated in the same way as the new hosts when it comes to their status and group membership. New groups are added if required, but existing group memberships won't be affected. If the status field is not provided then the initial host status will be automatically decided following the account rules for newly discovered hosts.\nBy default, if a hostname with the www prefix is submitted, we strip the prefix and store only the parent domain. Our assessments always check both hostname variants. This behavior doesn't apply to special wholesale accounts.
