Filter out unnecessary dataplane logs (sonic-net#21271)

PR sonic-net#21045 for fixing compatibility issues of docker-sonic-mgmt upgrade removed the hook for setting log levels of couple of loggers.

The code for setting log level of ansible loggers is no longer needed after previous ansible upgrade a few years ago.

However, setting log level for the 'dataplane' logger is still necessary.

This change added back the code to set log level for the 'dataplane' logger to avoid unnessary logs when 'ptfadapter' is used in test script.
