pass all command line arguments to cqlsh

command line arguments to cqlsh aren't passed along by the wrapping shell script, this change fixes that.

behaviour before change:

    $ cqlsh 192.168.200.11
    Connection error: Could not connect to localhost:9160

behaviour after change:

    $ cqlsh 192.168.200.11
