Describe what this PR does / why we need it

This pull request updated area of sealer's log.

Currently, end users bear a lot on sealer's log. There are lots of cases where end user could not recognize the log's meaning, even if he is a senior k8s or sealer engineer. We have to say sealer's log needs improvement.

First, just make the error message and log message readable, to satisfy normal user's English reading.
Second, provide helpful information as sufficient as possible.

And This pull request went through all log and error code of sealer project, and improved them within itself.

In the future, we still keep pace with user's input to improve log and error, such as: improving the accurate embedded message, shorten log information with continuous arch improving.
