    bitbake: xmlrpc: implement check of connection to server
    
    Implemented check_connection function. The purpose of this function
    is to check if bitbake server is accessible and functional.
    To check this this function tries to connect to bitbake server and
    run getVariable command.
    
    This API is going to be used to implement autoloading of bitbake
    server.
