logs: provide option to display log

This is a very basic display that just dumps the formatted json data of
the xyz.openbmc_project.Logging.Entry interface. There is much more that
could be done here but this is 100% more then what we have and could be
built upon later if found useful.

Tested:
root@witherspoon:~# obmcutil showlog /xyz/openbmc_project/logging/entry/54
{
	"type" : "a{sv}",
	"data" : [
		{
			"Id" : {
				"type" : "u",
				"data" : 54
			},
			"Timestamp" : {
				"type" : "t",
				"data" : 1589483560788
			},
			"Severity" : {
				"type" : "s",
				"data" : "xyz.openbmc_project.Logging.Entry.Level.Error"
			},
			"Message" : {
				"type" : "s",
				"data" : "xyz.openbmc_project.Common.Error.Timeout"
			},
			"AdditionalData" : {
				"type" : "as",
				"data" : [
					"CALLOUT_INVENTORY_PATH=/xyz/openbmc_project/inventory/system/chassis/motherboard",
					"TIMEOUT_IN_MSEC=5"
				]
			},
			"Resolved" : {
				"type" : "b",
				"data" : false
			},
			"UpdateTimestamp" : {
				"type" : "t",
				"data" : 1589483560788
			}
		}
	]
}
