Add get/set boot option ipmid command support with correct DBUS property handling.

1) Add support for IPMI get/set boot option command.
    a) boot options stored in dbus property.
    b) IPMI get boot option command get boot option from the dbus
    property.
    c) IPMI set boot option coomand set boot option to the dbus
    property.
2) Two methods to handle the dbus property set and get:
    a) dbus_set_property()
    b) dbus_get_property()
3) The property is stored as a 10 character strings which representsd 5-byte information.
4) ipmid set method is registered and implemented since petitboot will use it to clear the boot options.
5) Get service name via object mapper
    a) The connection name is got via objectmapper.
    b) The method used to get the connection name is object_mapper_get_connection().
    c) dbus_get_property/dbus_set_property will get the connection name via the above method instead of hard coding.
6) The boot option is made human readable (done by Chris).
