Describe the bug

It seems that we are leaking OTP in Hadoop payload logging

Expected behavior

We shouldn't be logging OTP.

Screenshots

Machine version (please complete the following information):

• OS: Windows or Linux

Tasks

• Fix up logging level in Hadoop plugin
  • Do not forget to rebuild the plugin
• Fix the regex in OTPFormatter
  • Store the OTP character set in common and use it in OTPFormatter and AuthenticationFacade.generate_otp()
  • Compile regexes as class variables so they don't need to be recompiled for every single log message
