Previously, when the preferred json mapper was set to Gson, the Gson
HTTP message converter was added before any other converters. This
changed the form of String responses that were already valid. When
Jackson is in use, a string converter is used as it appears earlier
in the list than the Jackson converter. When the mapper is switched
to Gson, the Gson converter is added first in the list of converters
and the Strong converter is no longer used. This results in the
String, that was already valid JSON, being converted again. This
changes its form as quotes are escaped, etc.
This commit updates HttpMessageConverters so that the Gson converter
is added to the list immediately before the default Jackson
converter. This is done by considering the Gson converter to be an
equivalent of the Jackson converter.

This is a follow-on from 3fec4110 which only considered
BatchDataSourceInitializer as a possible initializer of Batch's
database schema. Flyway and Liquibase are now also considered.
Closes gh-27193
Prior to this commit, `NettyProperties` would use `DISABLED` as the
default level for leak detection in Netty. This is not the default value
enforced by Netty, which is `SIMPLE`.
This commit changes the default configuration property value and ensures
that both stay in sync.

The auto-config requires Spring JDBC for DataSource creation from
spring.flyway.url or spring.liquibase.url, checking Flyway migrations
exist, etc. Without it, the application fails to start due to missing
spring-jdbc classes.
This commit updates the auto-config so that it backs off in the
absence of spring-jdbc.

`R2dbcInitializationConfiguration` that was stopping
custom username/password properties from being applied.
