Generate current model changes into db/changelog/dev (#260)

With this PR the following changes are made:
- Also generate a delta DDL sql for current model changes against model
v2.
- Also deploy current CDS development model as delta DDL sql to Postgres
with Liquibase
- Ensure that the Postgres testcontainer instance is also restarted to
avoid Liquibase issue due to modified changeset context for current dev
DDL sql.
