Some of the attributes printed as JSON by opticsmon are common to all
PCI adapters factor these out into reusable helper functions
zpci_adapter_json_print_start() and zpci_adapter_json_print_end().

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.
