ConstantSystemConfigProvider is an implementation of SystemConfigProvider which always returns the same value.

SystemConfig embeds a SystemConfigEntries message which contains an entry for every system descriptor (e.g.

SystemConfigMask is a mask that can be applied to a set of system config entries to filter out unwanted entries.

SystemConfigProvider is capable of providing the SystemConfig, as well as notifying clients of updates to the SystemConfig.
