UX: Sumo Logic integration

[mathnogueira]

Description

We are adding a new integration for Sumo Logic (#3423), so we need to design a new data store screen for it to be configured.

To configure the integration, we need three fields:

Endpoint: https endpoint to the Sumo Logic deployment (e.g. https://service.sumologic.com/)
Access ID: id of the access key (14 characters) (e.g. oy6MVyDivotH2M)
Access Key: password of the access key (64 characters) (e.g. nm96ldyyiJs7iEJFHfqWNC9n3UxwaCWs50O1cUyUFCYQjHyDaxfpWYblck4cnltL)

Those values were randomly generated.
