Changes to display shared network when router:external filter is provided. Also made changes to avoid duplicates in the result
1. Store router-external in create and update (in DB)
2. Added a function to query vn’s with “router-external” flag set.
3. Fix for access of context.
4. Set the router-external flag in net-show using this flag from DB rather checking _fip_pool_ref_networks
fixes to get_networks
Support for router-external flag from OFF -> ON
Fix issue where non-admins do floating-ip-list
In net-list for non-admin role gather router:external nets also in collect phase. Remove non-admin functionality in branches with admin role
