[UI] On a tor scale setup, unable to edit a port('Error in getting port data')

[Vedamurthy Joshi]

R2.1 36 Ubuntu 12.04.3 Icehouse

This is a TOR scale setup with 11K ports.
In Configure> Networking> Ports page, I chose a port and opted to edit it.

After about 30 seconds, i get the error as shown in attachment (Error in getting port data)
Sometimes, this error dialog doesnt show up, but still the current port properties are not loaded in the dialog

using new api to read the vmi object in port popup.

Reading teh whole VMI object in the create/edit of popup was leading to block of
all available port in nodejs to avoid the new api is used to read only the
instance IP .

Also included map limit for Interface pages.
used global variable global.ASYNC_MAP_LIMIT_COUNT.

#1442002 - Increase the time limit of the port response.
#1442118 - Remove the instance ip from VMI call in popup
#1442374 - port scaling issues
-> Single call to get current project's vn and shared vns.
-> In case of edit. We can just get port's parent vn. No need to get all vn's.

All the three bug specified above will be solving this bug.
