This patch removes the usage of eventlet in the Metadata Agent. The new metadata proxy is based on the implementation done in [1]. This new new implementation mimics the implementation of the ``UnixDomainWSGIServer`` class. The server listens to a file socket that is populated by the HAProxy instance running inside the network metadata namespace. The HAProxy writes the requests of the virtual machines on the Unix file socket and the metadata proxy sends the requests to the Nova metadata server. This implementation doesn't use ``oslo.services`` to spawn the processes or the local threads depending on the ``metadata_workers`` configuration variable. Right now only the embedded form (local thread) is implemented (metadata_workers=0, the default value). Future implementations will enable again this configuration variable.
