NFD

The authorize section in NFD configuration specifies how to validate NFD command interest.
For some NFD command interest (such as Face management), validation may not be required.
Therefore it would be desired to support wildcard in the authorize section.
An example would be:

authorize
{
  certfile any
  privileges
  {
    faces
  }
}

Since NFD use CommandInterestValidator, this change also requires CommandInterestValidator to support wildcard.
