Ability to configure IP address for VIC Appliance in HTML5 plugin

[arslanabbasi]

User Statement:

VIC appliance might be sitting behind LB/NAT so it won't be directly reachable from vCenter using appliance IP. In these scenarios, there is a need to change vic appliance IP in HTML5 client.

Details:

vCenter IP: 10.40.206.195 VIC Appliance IP: 192.168.10.101 - NSX Network sitting behind NSX Edge NSX Edge DNAT IP for VIC Appliance: 10.40.207.140

In the above scenario, 192.168.10.x/24 network is not accessible directly from vCenter. I was able to download and run ./install script using "10.40.207.140" IP for vic appliance. However, the HTML5 plugin started using the IP of vic appliance that is shown in vCenter. This is a valid case but user should have the ability to change this in corner cases like these.

Without this configuration ability, there is unnecessary dependency that vCenter should be able to reach VIC appliance!

Acceptance Criteria: Ability to change VIC appliance IP in HTML5 Client. It can be either VIC appliance IP field in UI or a flag when running the ./install or ./upgrade script for installing vcsa plugin.
