About the commit

The following commit provides a functionality to invoke a startup script (after reading all the configuration files)
This startup script generates passwords with rotation (with timeout rotate_frontend_password_timeout) for the frontend end user even if the frontend users file doesn't exists i.e -F is not provided.

It operates by creating new frontend users in the system by taking usernames from file provided in -u option i.e. pgagroal_database.conf and generating random passwords for the newly created frontend_users.

Condition for startup function to work:-

• number_of_frontend_users should be 0
• rotate_frontend_password_timeout should be non-zero
