ParameterMgr: Add more tuning methods to the C++ public API

These methods are:

 - renameDomain
 - setSequenceAwareness
 - getSequenceAwareness
 - renameConfiguration
 - setElementSequence
 - setApplicationRule
 - getApplicationRule
 - clearApplicationRule

The "remote tuning" methods are also modified to use them instead of directly
accessing inner objects and the tuning mode checking is moved to the public C++
method when applicable.
