The system keyspace has a replication factor of 1 and is local to each
node; it is therefore recommended to query system.local with a
consistency level of ONE or LOCAL_ONE.
Stronger consistency levels may result in an Unavailable error, but this
does not mean that the node is down.

Previously, a condition checked the value of "spring.datasource.url" to
determine if an embedded database has to be created as a fallback. When
the value is set with an unresolved placeholder, this fails even if
the DataSource is going to created by another mean ultimately.
This commit makes a more conservative check by only checking the
presence of the property rather than its value.

Previously, the presence of a `ConsumerFactory` bean would make the
auto-configured one to back off, leading to a failure down the line if
no available instance matches the generics criterion. This commit
improves the auto-configuration to create a `ConsumerFactory<?,?>`
behind the scenes if none is available.
Closes gh-19221
Previously, DependencyCustomizer's ifAllResourcesPresent method
would return a customizer that added modules if any of the resources
were present. This commit corrects this behaviours so that modules are
only added if all resources are present.
Fixes gh-20418
TomcatReactiveWebServerFactory's getTomcatWebServer is described as
being a hook point the can be overrideden to return a different
TomcatWebServer or to apply additional processing to the Tomcat
server. Previously, this did not work as the method was not called
to create the TomcatWebServer instance. Instead, TomcatWebServer was
instantiated and returned directly.
This commit updates TomcatReactiveWebServerFactory to call
getTomcatWebServer to create the TomcatWebServer instance. A test
has also been added to verify that the method is now used.
Fixes gh-20386
