xApp configuration file

The configuration file of the xApp needs to be in yaml file with strict 4 spaces. This facilitates the parsing. The configuration of the xApp needs to have at least the following fields:

xapp:
    ip_ric: 127.0.0.1
    e42_port: 36422
    # IP to bind SCTP client
    # Needs to be in the range of
    # ip_ric. It is the interface
    # from ifconfig cmd
    ip_xapp: 127.0.0.1
    log: 2
        # trace: 0
        # debug: 1
        # info: 2
        # warn: 3
        # error: 4
        # fatal: 5
        # e.g., level = 2 -> level = info
    # Comment the database section
    # if no database is needed/used
    db:
        ip: 127.0.0.1
        dir: /tmp/
        filename: testdb
        usr: xapp
        psw: BubbleRAN
