SaaS Connector Configuration - Testing a Connection

[adriaaaa]

Description

This ticket was split out of #761. The scope of this ticket is limited to developing the section of the screen that will display test connection results

Assumptions

Acceptance Criteria

1. Demonstrate that a user can perform a test to see if they are able to connect to their instance of that application.
2. The "Test Connection" button should be disabled until the params are saved
3. Confirm that the results of the connection test are displayed on the screen
4. this includes Success or Error, the timestamp of the connection test, and the Success or Error message (note we will need to look to see if the error messages are something that is user-friendly, if not then do not include the message, just the fact that it errored).

Mockups
