This commit removes all legacy config props metadata files
named `dataflow-configuration-metadata-whitelist.properties`.
This is safe with respect to SCDF because stream apps 4.x
require SCDF 2.11.x to launch the apps. Therefore, no existing
SCDF customers on an older SCDF version (that only supports
the legacy file) will be impacted - the users will all be on
the latest version of SCDF.
Fixes#252
* Renamed spring-configuration-metadata-whitelist.properties (removed "-whitelist")
* Renamed spring-configuration-metadata.properties to
dataflow-configuration-metadata.properties
* Fix rsocket
* Rsocket props now added back in
* Rename rsocket-sink metadate file to non-legacy format
