Add libs folder and install_libs.sh

Add libs folder and install_libs.sh

The following tasks are done:
1. Moving all the libraries (loblib.sh) to lib folder.
2. Adding a script "install_libs.sh" whose job is to move all the libs
   to linux internal folder (/usr/local/lib/aimlfw/libs) and updating
   bashrc to setup env-variable AIMLFW_LIBS_HOME, so that script is only
   required to run only first time.
3. Usage example at "install_k8s.sh"
4. Adding uninstallation_libs script to remove the linux internal folder
   and env-variable AIMLFW_LIBS_HOME from bashrc.
