pldmd, requester, softoff & utilities: Improving logs (lg2)

This commit corrects the severity level of logs and also formats the
message string, fixing the ill-defined message string of the logs as
mentioned in the anti-pattern document [1]. Additionally, based on the
requirement this commit adds more debug information to logs.
