Swap data and properties

/resources/{resourceId}/properties -> /resources/{resourceId}/data.
X-OADA-File-Metadata became X-OADA-Resource-Properties. This name scheme better
maps to typical file systems and makes the meaning of /data more clear.
/configs now a hierarchy that maps to a resource

/config/what/ever/hierarchy/you/want maps to a resource id and href that
contains the actual configuration.
Authorization and access_token for all endpoints

Made the Authorization header and access_token query parameter show for all
endpoints.

They where added to the global *common definition, however, it seems securedBy
should accomplish this. Need to investigate with api-console as to way
securedBy is not sufficient.
