Stop updating deployed app attribute after VM Properties refactor in CloudShell

[alonagetzler]

a new "VM Properties" side pane is going to be added in 7.2 so we won't need to populate the attributes on the deployed apps (public ip, user and password).

QualiX will need to know how to access VM properties to get the user/password and maybe also the private ip, so it won't depend on the deployed app address and attributes. At this stage we can also update the logic of populate the deployed app address so it will show private ip only if there is no public/elastic ip. (#245)

This refactor should also be applied to vCenter shell if we populate some deployed apps attributes/address there.
