Subject: [PATCH] debian: Don't require ipsec_local_ip to configure IPsec

Commit e97a103 (Open vSwitch: ovs-monitor-ipsec: Add ability to traverse
NATs) removed the requirement that the "ipsec_local_ip" key must be set
to use IPsec, but other code and documentation was not updated to
reflect this.  This commit does that.
