Optional single database bootstrap

[smohiudd]

Description

The current WFS staging features api has a single database and user while veda-features-api-cdk sets up two databases; one admin and the other "new user" that contains the data. This causes an issue when creating an rds with a snapshot from the WFS features api. The databases and users of the snapshot and veda-features-api-cdk rds bootstrap do not align so the features API is not able to see the snapshot data.

We will need to create an optional switch that creates a single database and user so features api will be able to work with a snapshot from wfs features api.

Acceptance Criteria

• Optional single database and user when bootstrapping rds
