Based on a question posted by a user, this patch implements the feature of allowing sleep function at cfgutils module receives a pseudovariable argument.
This patch is a very first approach, and in case of being accepted, it could be applied to usleep function too.
A couple questions:
1. What should be the module's behaviour when argument as invalid value/format (Ignore/log the error, or stop execution?)
2. Should the current behaviour be kept? That is to say, still receive a string as argument, or should it be completely overrided by pseudovar usage? In case that it should be kept, is there a way to do it in the same function? As I see, a new function should be implemented, as fixup functions are different for pseudovar and string.
Thanks in advance for your attention.
