BUG#: 9928

TITLE: Initial FQL implementation per DMTF specification DSP0212

DESCRIPTION: Commit of initial FQL (Filter Query Language)
implementation including 1) FQL parser and evaluator, 2 FQL integration
into CIMOperationRequestDispatcher.cpp, 3)FQL unit and end-end tests
in FQL/tests/Parser and FQL/tests/clitest and FQL tests added to
cimcli tests in src/Clients/cimcli/tests/Makefile
