[Ingest Manager] Prevent user from adding more than 1 Endpoint data source

[hbharding]

For technical reasons, there can only be 1 endpoint datasource per agent configuration. We need to prevent the user being able to add a 2nd endpoint datasource if one already exists, and we may want to include an explanation why.

After talking with the group:

When adding an integration from an agent configuration page, simply don't show the Endpoint integration in step 1 where we list available integrations if Endpoint is already configured for an agent config. This prevents the user from being able to add a 2nd Endpoint integration to the same config.

When adding an integration like Endpoint from an integration detail page, in step 1 where user selects an agent configuration, we will show the agent configurations as disabled if they already have Endpoint configured.

Cool. Thanks @hbharding for posting that. Just to be clear, although you detail the UI changes above, the enforcement of this will also still be done at the API level, correct?

@paul-tavares Yes we should make sure to do this at API level too.
