Return a HTTP404 message when the Metadata instance is not present
If the Metadata instance (network, router) is not present, now the
Metadata proxy handler writes a HTTP 404 error message in the socket
file that is received by the client (virtual machine) that requests
the metadata.

Title:
Fix metadata return code when the instance is not present
Status in neutron:
Fix Released
Bug description:
Since [1][2], both the Metadata agent and the OVN Metadata agent do
not return anything if the instance is not found. That was marked as a
TODO in [3][4].
The goal of this bug is to address this TODO and return the proper
HTTP 404 error to the metadata client.
