Retry till routing-instance has route-target reference.

With change of creating native RI synchronously in api-server, it
is no longer the case that RI will have RT on first read (schema
transformer sets the RT ref).

config: sync native-ri create/delete vmi->native-ri ref.

Synchronously create the 'native' routing-instance for a
virtual-network. Also when a virtual-machine-interface is
created, link it to the native routing-instance in the same
context. To achieve this following refactoring is done:

1. create a ApiContext object which will be present
in every request as a 'thread'-local-variable.
2. ApiContext will hold a reference to a <request> object
which could be bottle.request(external) or ApiInternalRequest
which would be requests generated from within api-server.
3. Replace occurences of bottle.request with get_request()
to normalize request structure.
4. Rename and add more interactions from request handling
layer to type-specific handling layer with <pre|post>_dbe_<CUD>
5. Have ApiContext hold a list of undo_callables so that
callee can add to undo-list and caller on any error will
iterate and invoke undo callables.

Fix the usage of default_ri_name

default_ri_name now stores fq name of the ri. We should not prepend vn's fq name
to get it
