Comment from component owner

1. I see that the documentation is very specific to RDKB and how to use it. This will be changed in 2604.
2. The existing documents are deleted but pl restore it.
3. The new document that must be talking about how rdklogger works; how log4c is fitting within rdklogger; and how it is portable to replace underneath log4c with any new library.
4. Remember, RDKB is one of the profile that uses it. But we do have RDK-V, RDK-E, RDK-C using the same.

Thanks,
