Clean log

[nocvalight]

Motivation:

since registry-data.log，registry-session.log，registry-exchange.log, cache-digest.log print too much, and currently log is split by day. The log file is too large and the server disk will be easily full up.

Result:

Fixes #<139>.

If there is no issue then describe the changes introduced by this PR.
#139
