This directive is deprecated in Apache 2.4+, and so should be removed at some point.

Provision_Context_server->verify dispatches to verify_server_cmd instead of verify.

The $db_port can be empty if weird things happen to context on the fly, because it is a server and not site specific variable, thus $this->server->db_port should be used directly here.

Issue #2259461 by Liam McDermott - Remove too aggressive limit_conn directive in the Nginx config templates.

This reverts commit abc9ac9c.
