- Changed datasource configuration so that if datasources other than the
  one for the default-group-name (transactional) are not specified then
  the default-group-name one is used. There is a similar change for the
  TenantDataSource so that only the one for the default-group-name
  (transactional) is required for each tenant.
- Changed the Derby database default configuration to use a single
  MoquiDEFAULT database instead of separate transactional, analytical,
  nosql, and tenantcommon databases. Also changed the EXAMPLE1 tenant to
  use the tenantId as the database name, setting a pattern for other
  tenants.
