Introduce the concept of a generic zPCI device monitor by creating the zpcimon_ops operations struct turning all optics specific calls into abstract monitor calls. Handle monitors as a static array of zpcimon_ops based monitors of which the now split out optics monitor is currently the only one. All operations are in principle optional though a monitor which provides an init operation must also provide the corresponding destroy operation. Keep the base64 based JSON pair as non optics specific for later re-use and make it just skip the output in the very unlikely case that encoding fails. In follow on commits a monitor for NVMe devices collecting SMART data will be added.
