[PFW] Access Configurations directly

BZ: 88357

This patch aims to enable direct access to Configurations
without using the main blackboard. 2 additional commands are
available:
- getConfigurationParameter <domain> <configuration> <param path>:
Get value for parameter at given path from configuration.
- setConfigurationParameter <domain> <configuration> <param path> <value>
Set value for parameter at given path to configuration.
