Charmed MongoDB

Internal users explanations:

The operator uses the following internal DB users:

• operator - the user that charm.py uses to manage database/cluster.
• monitor - the user for COS integration.
• backup - the user to perform/list/restore backups.

The full list of internal users is available in charm source code. The full dump of internal users (on the newly installed charm):

Note: it is forbidden to use/manage described above users! They are dedicated to the operators logic! Please use data-integrator charm to generate/manage/remove an external credentials.
