Bug description:
  MySQL has some logic for ensuring passwords aren't written to the
  logs, detailed at https://dev.mysql.com/doc/refman/5.7/en/password-
  logging.html (passwords are rewritten before they are logged).
  However, a failed grant statement is written unaltered to the error
  log, bypassing the password rewriting logic.

  [Impact]
  Ubuntu's bug reporting system will suggest uploading the error log to a bug report. This can lead to user credentials written in plain text in public bug reports.

  [Test case]
  (note/todo: I had a simpler test for this, but can't find the exact syntax for it)
  * Add the following to the server config:
  plugin-load=validate_password.so
  validate-password=FORCE_PLUS_PERMANENT
  and restart the server
  * Log in and run GRANT ALL ON *.* TO 'user'@'localhost' IDENTIFIED BY '123';
  * Observe statement failing because it doesn't follow password validation rules
  * Run "ubuntu-bug mysql-server"
  * Choose "View Report"
  * Search for "123"

  Expected behavior:
  Password is scrambled or otherwise not written to the apport report

  Actual behavior:
  The entire failed grant statement is written to the apport report

  [Regression Potential]
  The fix replaces all lines in the log that contain any of the terms mentioned on the password-logging site, so it will rewrite more lines than strictly necessary, potentially making debugging harder.
