[fuelclient] Shlex does not accept unicode input prior to python 2.7.3

[Sylwester Brzeczkowski]

Now it's impossible to test commands which content unicode in fuel2 using BaseCLITest class:

    def exec_command(self, command=''):
        """Executes fuelclient with the specified arguments."""

        return main_mod.main(argv=shlex.split(command))

Possible solutions are:

- drop python 2.6
- replace shlex with something else (custom function or some third-party module)
- change all test to pass list of arguments instead of string to 'exec_command'

This seems to me as tech-debt bug as we are not dropping support for py26 and AFAIU will not in near future. Also workaround is available [1]

We passed SCF in 8.0. Moving the bug to 9.0.
