Akihiro Motoki 50d54bb007 log_method: get logger from decorated method if unspecified
This commit makes 'log' optional.
'log' attribute of each command class does not exist
when the class is defined because 'log' is now setup
dynamically when a class is instantiated. Instead log_method
looks for a logger from a decorating method.

compute.v2.server is changed in this commit as an example.
