This introduces a rate limit to new connections created by a worker.
Right now it will simply send a VN, but eventually this will only issue a RETRY for unverified initials.

Summary:
The `QuicServerWorker` routing layer only retains mapping of a
single cid -> transport pair. However, in the case of two different
connections eventually having the same CID, both of those connections
will each believe they have that CID, while the routing layer
will only route to one of them.
When one connection is closed and the mappings are removed for all of its CIDs,
this MAY close the other connection inadvertently.

Summary:
Currently, before server generate the destination CID, we route packets with client's address, port and client's source connection ID. But now that client can use 0-len source connection ID, the different connections from the same client address and port will be routed to the same server connections.
This diff changes it to use client's initial destination connection ID as part of the routing key.

Summary:
Before any CID is available, the source address routing
table might be the only owner of the transport. Removing the transport from
there deletes the transport. connectionIdData param is a const ref to a member
of the connection state owned by the transport. So deleting transport also
deletes this vector, which makes the const ref invalidated.
