CLOUDSTACK-10003 automatic configure juniper srx/vsrx nat loopback, (#2184)

Browse Source 
Automatic configure juniper srx/vsrx nat loopback,

Constraint condition that manual configure source nat in juniper srx，allowed vm vist public network :
zone : trust to {trust,untrust}
rule : source address {0.0.0.0/0},destination address{0.0.0.0/0} ,do source nat with pool {public network getway ip}.

code change for trust to trust destination or static nat:

1. add srxCommand :CHECK_PRIVATE_IF_EXISTS. for add/delete rule to detect whether exist or not contain DestinationNatRule or StaticNatRule (ruleName_private) in trust zone .
2. add DestinationNatRule  (ruleName_private) to trust zone when ADD DestinationNatRule to untrust .
3. delete DestinationNatRule  (ruleName_private) from trust zone when DELETE DestinationNatRule from untrust.
4. add StaticNatRule (ruleName_private) to trust zone when ADD  StaticNatRule to untrust .
5. delete  StaticNatRule (ruleName_private) from trust zone when DELETE  StaticNatRule from untrust.

Check private if exist.
