Fix proxy_http_version.  This happened as a result of a merge conflict
introduced in commit 7d9c234e.  I've reviewed the PRs against hsmaster
and do not see that commit in any of them.  The conflict was created
while I was using a branch called new_parameters_merge where I merged
all my separate feature branches into one in order to do some testing
with my test hosts.  That conflict then made its way into hsmaster.

Fix proxy_http_version.
Replace  http_additional_array with http_cfg_{pre,ap}pend which is a
hash and is the same way nginx::resource::location handles additional
config.
