Add recursive variant of Config.getNames() methods
These methods allow to find all configuration entry names for a given section or section/subsection searching recursively through all base configurations of the given configuration. These methods are needed to calculate the names for the effective configuration of a git repository which combines the configuration entry names found in the repository, global and system configuration files Bug: 396659 Change-Id: Ie3731b5e877f8686aadad3f1a46b2e583ad3b7c6 Signed-off-by: Matthias Sohn <matthias.sohn@sap.com>
