Subject: get-log: Make log identifier a required parameter
Git-commit: 44044e6c3c6fc1d4813163d5054c0750ef88ee06
References: bsc#1086240
Patch-mainline: v1.6

If you're using the generic get-log, make sure the user specifies the
log parameter. It would be a user error if they don't as they should
never be counting on a default parameter.
