Describe the bug
The template.yaml files contains the following environment variables:

SSOSYNC_GOOGLE_CREDENTIALS: !Ref AWSGoogleCredentialsSecret
SSOSYNC_GOOGLE_ADMIN: !Ref AWSGoogleAdminEamil
SSOSYNC_SCIM_ENDPOINT: !Ref AWSSCIMEndpointSecret
SSOSYNC_SCIM_ACCESS_TOKEN: !Ref AWSSCIMAccessTokenSecret

These variables, however, are not actually used in the source code. Instead secrets.go contains hard coded values.

Expected behavior
Environment Variables should be used to allow configuration of the ssosync app.
