Bug Description

Based on https://bugzilla.redhat.com/show_bug.cgi?id=1912688

the problem is that central stack (for an example EDGE DCN case) creates its owner VIP resources, and these VIP resources appear in /etc/hosts.
Host records of the central stack including host records of vip resources in the central stack are injected to edge stacks by ExtraHostFileEntries and this is why these hosts entries are duplicated.

We should not include Vip hosts entries in edge site (or ideally we should not create these vip resources to save IP allocations).

    Dedup host entries in the exported data for stacks

    Do not add extra host entries for VIPs for stacks deployed off the
    exported data, since it already contains those entries

    This is done by setting AddVipsToEtcHosts to False.
    Then a stack is deployed, no more VIPs will be added into /etc/hosts
    of the targeted hosts.
