log-create: add CLI utility to create events

Add utility to allow creation of events from the command line and
shell scripts.  The utility ensures that the correct data arguments
are passed, or else fails the creation.

Tested:

```
$ ./builddir/log-create xyz.openbmc_project.Sensor.Threshold.SensorFailure --json '{ "SENSOR_NAME": "Example-Sensor" }'
