Itential adapter to connect to mongo

## Enhancements

### Adding a Second Instance of an Adapter

You can add a second instance of this adapter without adding new code on the file system. To do this go into the IAP Admin Essentials and add a new service config for this adapter. The two instances of the adapter should have unique ids. In addition, they should point to different instances (unique host and port) of the other system.

### Adding Adapter Properties

While changing adapter properties is done in the service instance configuration section of IAP, adding properties has to be done in the adapter. To add a property you should edit the propertiesSchema.json with the proper information for the property. In addition, you should modify the sampleProperties to have the new property in it.

```text
Files to update
* propertiesSchema.json: add the new property and how it is defined
* sampleProperties: add the new property with a default value
* test/unit/adapterTestUnit.js (optional but best practice): add the property to the global properties
* test/integration/adapterTestIntegration.js (optional but best practice): add the property to the global properties
```

### Enhancing Adapter Integration Tests

The adapter integration tests are written to be able to test in either stub (standalone) mode or integrated to the other system. However, if integrating to the other system, you may need to provide better data than what the adapter provides by default as that data is likely to fail for create and update. To provide better data, edit the adapter integration test file. Make sure you do not remove the marker and keep custom code below the marker so you do not impact future migrations. Once the edits are complete, run the integration test as it instructs you to above. When you run integrated to the other system, you can also save mockdata for future use by changing the isSaveMockData flag to true.

```text
Files to update
* test/integration/adapterTestIntegration.js: add better data for the create and update calls so that they will not fail.
```

As mentioned previously, for most of these changes as well as other possible changes, there is more information on how to work on an adapter in the <a href="https://docs.itential.com/opensource/docs/adapters" target="_blank">Adapter Technical Resources</a> on our Documentation Site.
