Subject: [PATCH 1/3] Add DB_APPENDIX to support additional parameters With
 https://github.com/Mailu/Mailu/pull/3701 the remark was left to set the DB
 collation for MariaDB setups. However, the Helm chart has no option to
 overwrite the SQLAlchemy URI really. It selfs DB_USER, DB_PW, DB_NAME and
 DB_HOST and thus triggers the Alchemy URI to be overwritten (and it
 overwrites it statically as well...). This commit adds the parameter /
 environment variable DB_APPENDIX allowing for, e.g.,
 '?collation=utf8mb4_unicode_ci' to be set using an environment variable which
 the Helm chart can then set.

 `````````````````````````````````````````````````````````````
 
 If the admin container is `unable to connect to an external MariaDB database due to incompatible collation`_, you may need to change the ``SQLALCHEMY_DATABASE_URI`` setting to ensure the right connector is used.
+Alternatively, you may set ``DB_APPENDIX`` accordingly. For example: ``?collation=utf8mb4_unicode_ci`` is appended as is just after the database name in case DB_TYPE and related values are set.
 
 MariaDB has no support for utf8mb4_0900_ai_ci which is the new default since MySQL version 8.0.
