Improve documentation around database plugins (#8892)
* Adds a summary to the top of each plugin's page showing the capabilities that the plugin has.
* Fixed sidebar sorting (they weren't quite alpabetical)
* Improved instructions for using the Oracle plugin
  * Added note about using the pluggable database rather than the container database
* Replaced admin/root usernames with super-user ones to encourage users to not use the root user in Vault
* Included suggestions to rotate the root user's password when the plugin is capable
* Improve documentation around rotating the root user's password
* Fixed various typos

# MongoDB Database Secrets Engine
MongoDB is one of the supported plugins for the database secrets engine. This
plugin generates database credentials dynamically based on configured roles for
the MongoDB database and also supports
[Static Roles](/docs/secrets/databases#static-roles).
See the [database secrets engine](/docs/secrets/databases) docs for
more information about setting up the database secrets engine.
## Capabilities
| Plugin Name | Root Credential Rotation | Dynamic Roles | Static Roles |
| --- | --- | --- | --- |
| `mongodb-database-plugin` | No | Yes | Yes |
## Setup
1. Enable the database secrets engine if it is not already enabled:
```text
$ vault secrets enable database
Success! Enabled the database secrets engine at: database/
```
By default, the secrets engine will enable at the name of the engine. To
enable the secrets engine at a different path, use the `-path` argument.
1. Configure Vault with the proper plugin and connection information:
```text
$ vault write database/config/my-mongodb-database \
plugin_name=mongodb-database-plugin \
allowed_roles="my-role" \
connection_url="mongodb://{{username}}:{{password}}@mongodb.acme.com:27017/admin?tls=true" \
username="vaultuser" \
password="vaultpass!"
```
1. Configure a role that maps a name in Vault to a MongoDB command that executes and
creates the database credential:
```text
$ vault write database/roles/my-role \
db_name=my-mongodb-database \
creation_statements='{ "db": "admin", "roles": [{ "role": "readWrite" }, {"role": "read", "db": "foo"}] }' \
default_ttl="1h" \
max_ttl="24h"
Success! Data written to: database/roles/my-role
```
## Usage
After the secrets engine is configured and a user/machine has a Vault token with
the proper permission, it can generate credentials.
1. Generate a new credential by reading from the `/creds` endpoint with the name
of the role:
```text
$ vault read database/creds/my-role
Key Value
--- -----
lease_id database/creds/my-role/2f6a614c-4aa2-7b19-24b9-ad944a8d4de6
lease_duration 1h
lease_renewable true
password 8cab931c-d62e-a73d-60d3-5ee85139cd66
username v-vaultuser-e2978cd0-
```
## Client x509 Certificate Authentication
This plugin supports using MongoDB's [x509 Client-side Certificate Authentication](https://docs.mongodb.com/manual/core/security-x.509/)
To use this authentication mechanism, configure the plugin:
```text
$ vault write database/config/my-mongodb-database \
plugin_name=mongodb-database-plugin \
allowed_roles="my-role" \
connection_url="mongodb://@mongodb.acme.com:27017/admin" \
tls_certificate_key=@/path/to/client.pem \
tls_ca=@/path/to/client.ca
```
Note: `tls_certificate_key` and `tls_ca` map to [`tlsCertificateKeyFile`](https://docs.mongodb.com/manual/reference/program/mongo/#cmdoption-mongo-tlscertificatekeyfile)
and [`tlsCAFile`](https://docs.mongodb.com/manual/reference/program/mongo/#cmdoption-mongo-tlscafile) configuration options
from MongoDB with the exception that the Vault parameters are the contents of those files, not filenames. As such,
the two options are independent of each other. See the [MongoDB Configuration Options](https://docs.mongodb.com/manual/reference/program/mongo/)
for more information.
## API
The full list of configurable options can be seen in the [MongoDB database
plugin API](/api/secret/databases/mongodb) page.
For more information on the database secrets engine's HTTP API please see the
[Database secrets engine API](/api/secret/databases) page.
