MLIA-649 Strip mlia backend management into a new command

* add entry point for mlia-backend in setup.cfg and main.py
* add --force option for install from path: uninstall existing backend
  in ML Inference Advisor and install from given path
* add uninstall and list program parameters: uninstall has
  backend_name as input arg, install has backend_name as a mandatory argument
* add unit tests in test_cli_commands.py, test_cli_main.py,
  test_tools_metadata_common.py, test_tools_metadata_corstone.py
* updated README.md
* remove --download option for installing backend
* add new lines for the display section when we do mlia-backen list
* add case insensitive support for backend names in command line argument
