Change the BMC LogService to only display from the message registry

This change renames the existing BMC LogService that displays all
entries in the journal to a BMC Journal LogService.

The new standard BMC LogService is modified to only display messages
from the registry.  The registry MessageId and MessageArgs must
be included in the journal metadata as "REDFISH_MESSAGE_ID" and
"REDFISH_MESSAGE_ARG_<x>" respectively, where <x> is the arg
number from the registry.
