camel-yaml-dsl - Configuring bean properties should use key/value style

Yaml DSL has special beans configuration
https://camel.apache.org/components/next/others/yaml-dsl.html#_defining_beans

But the Camel DSL uses key/value style to be consistent across the DSLs (XML, Java etc) in the route template locale bean and other places

Using array with key/value also makes this much easier for tooling as the XML XSD and JSon Schema contract can know about this - otherwise its just "object" which can be anything.
