Add demo code for testing
This change add demo for using test mode flag lib in
self-instrumentation tests.
There are two options.
The option 1 is to create two versions, prod and test, of the library
using flags. The prod version library uses prod flag lib, and the test
version library uses test flag lib.
The option 2 is to dynamically link to the flag lib in the library. The
flag lib is used as a stub lib and is just used for building purpose.
The in the finally binary which uses the library, the binary should
statically link to the right version of the flag lib.
