[MidoNet] Admin Router vs. Provider Router

To stir up the router linguistics discussion...

IMHO, all names contains 'Edge' are ambiguous, we can have multiple edge
routers, which we need to distinguish from 'main' or 'service-providing

Also, whatever the name, it SHOULD live in services tenant, not admin
tenant. That is where services that do not belong to user tenants live
in OpenStack, admin tenant does not own anything at all. Having our
'Master-router' in admin tenant complicates privilege management by
requiring admin right in admin tenant (highest OpenStack privilege
possible) just to able to manage it, which can be dangerous (we had
several incidents related to this in the old MidoCloud).
