Closes gh-17777

Missing change logs would lead to an exception even
if the checkChangeLogLocation was set to false. Spring Boot's check
would pass but Liquibase would fail later making this property redundant.

This commit separates the auto-configuration of the `SessionFactory` in
an isolated class so that the rest of the auto-configuration is still
applied if the user provides a custom `SessionFactory` bean.

This significantly rework the auto-configuration to reflect the order
in which things are expected. Rather than keeping a conceptual cycle
between the builder and the two inner classes that are processed first,
the configuration is now split in three parts:

* The builder that is required and common
* The configuration when the HighLevelClient is available
* The RestClient configuration when that's not the case

Update `UndertowServletWebServerFactory` so that only our own mime type
