Fixed couple of other problems along:
* when expunge PF/Static nat rules as a part of vmExpunge/IpRelease process, first mark all rules as Revoke, and then send commands to the backend. Group commands by Ip address.
Before we used to do Revoke/Send per rule basis.
* When release source nat rule, make sure that corresponding vpn (if exists) is being expunged.
* added new fields to createIpForwardingRule api: startPort/protocol - required, endPort is optional
* updated "firewall_rules" table with a new field "is_one_to_one_nat" (being set when new rule is created)
status 7603: resolved fixed
Couple of other fixes:
* Set correct user_id for createVolume event instead of hardcoding it to System (1)
* Deploy dhcp vm when Zone's gateway provider is External Firewall and network is Virtual
