Clint 28447e00a3 Combined Database backend: Add Static Account support to MySQL (#6970)
* temp support for mysql+static accounts

* remove create/update database user for static accounts

* update tests after create/delete removed

* small cleanups

* update postgresql setcredentials test

* temp support for mysql+static accounts

* Add Static Account support to MySQL

* add note that MySQL supports static roles

* remove code comment

* tidy up tests

* Update plugins/database/mysql/mysql_test.go

* Update plugins/database/mysql/mysql.go

Co-Authored-By: Calvin Leung Huang <cleung2010@gmail.com>

* update what password we test

* refactor CreateUser and SetCredentials to use a common helper

* add close statements for statements in loops

* remove some redundant checks in the mysql test

* use root rotation statements as default for static accounts

* missed a file save
