Allows admin to control security-groups rule logging
NSXv distributed firewall expose an API to control rule logging,
as for the moment, admin user can use this feature only from inside of
the distributed firewall.
This patch make use of this API to provide the cloud admin with three ways
to control security-group logging:
- log whenever security-group rule is matched
- log when a packet doesn't match any security-group rule
- log whenever security-group rule is matched for selected
security-groups
