Remove duplicated take_action logging

This commit drops utils.log_method decorators.
As a result of logging refactoring in openstackclient [1],
utils.log_method decorator is no longer used in openstackclient
and we are planning to drop utils.log_method.

searchlightclient is the only project that uses log_method
decorator. take_action logging is duplicated, so we can safely
drop log_method decorator.

Once this patch is merged, openstackclient can drop utils.log_method
because there is no released searchlightclient.
