Bug Description

We are currently not setting metadata_workers when local metadata service on nova-compute hosts which results in automatically generated values based on number of cpus in the host. This results in more workers than required for systems with large numbers of cpus so we should make this configurable like the worker settings in the api charms.

Paste this link [1] for your reference, it proposes to use the following formula:

- for controllers: min(max($::processorcount, 2), $workers_max)
- for computes (DVR): min($::processorcount / 8 + 1, $workers_max))

I inadvertently removed the nova-compute target when this bug does actually require both neutron-openvswitch and nova=compute to support configuring the number of workers used for the metadata api/agent.
