refactor(log): use LOG_INFO_F instead of LOG_INFO (3/3)

[acelyc111]

apache#1305

This patch aim to use LOG_INFO_F instead of LOG_INFO for all the remain parts:

• Use LOG_INFO_F instead of LOG_INFO
• Use LOG_INFO_PREFIX instead of LOG_INFO for class proxy_session, pegasus_server_impl
• Use upper case for commands in class redis_parser
• Remove some commentted LOG_INFO code

TODO:

1. print dsn_primary_address in log is useless, since it must be itself in whose log, e.g. in src/common/fs_manager.cpp, src/replica/replica_stub.cpp
2. try to use LOG_*_PREFIX for class policy_context, cold_backup_context

Meticulous work! And LGTM!
Can we add some checking of parameter count in the log function?
