Assaf Muller e4a9a762a0 Forbid update of HA property of routers
While the HA property is update-able, and resulting router-get
invocations suggest that the router is HA, the migration
itself fails on the agent. This is deceiving and confusing
and should be blocked until the migration itself is fixed
in a future patch.
