Remove n-api-metadata service from compute nodes

Browse Source 
Starting up n-api-metadata service on every compute nodes does
not solve the problem of isolated networks (no route to metadata
service). It all depends on how 'enable_isolated_metadata' and
related options (e.g. force_metadata) are set in dhcp agent and
what is configured for the 'nova_metadata_host' option of q-meta
service. Having a global n-api-metadata service in the control
node is sufficient for a mult-node lab setup.
Besides, the n-api-metadata services on compute nodes are not
really working due to https://bugs.launchpad.net/nova/+bug/1815082

**Note:** the ``n-api-meta`` service is a version of the api server
that only serves the metadata service. It's needed because the
computes created won't have a routing path to the metadata service on
the controller.
