Stephane Nicoll 884c058e57 Add processor to generate configuration meta-data ... Adds an annotation processor to generates a JSON meta-data file at compile time from @ConfigurationProperties items. Each meta-data file can include an array or 'properties' and 'groups'. A 'property' is a single item that may appear in a Spring Boot 'application.properties' file with a given value. For example, 'server.port' and 'server.context-path' are properties. Each property may optionally include 'type' and 'description' attributes to provide the data type (e.g. `java.lang.Integer`, `java.lang.String`) and some short documentation (taken from the field javadoc) about what the property is for. For consistency, the type of a primitive is translated to its wrapper counterpart, i.e. `boolean` becomes `java.lang.Boolean`. A 'group' provides a higher level grouping of properties. For example the 'server.port' and 'server.context-path' properties are in the 'server' group. Both 'property' and 'group' items may additional have 'sourceType' and 'sourceMethod' attributes to indicate the source that contributed them. Users may use `META-INF/additional-spring-configuration-metadata.json` to manually provide additionally meta-data that is not covered by @ConfigurationProperties objects. The contents of this file will be read and merged with harvested items. The complete meta-data file is finally written to `META-INF/spring-configuration-metadata.json`.
