This commit makes sure that a "cache.time-to-live" property is not
generated for endpoints that do not have a main read operation (i.e. a
read operation with no parameter or only nullable parameters).

This matches the endpoint feature that provides caching for only such
operation.

  Use custom DataSource if Flyway or Liquibase has user or url

Closes gh-11751

This commit enables a more flexible Liquibase/Flyway configuration by
allowing for a combination of the provider's and the primary
DataSource's configuration to be used. This gives developers the
flexibility to specify only a user or a url and having
Liquibase/Flyway fall back to individual datasource properties rather
than ignoring the Liquibase/Flyway properties and falling back to the
default data source.
