encoding error when doing console log show

[Thomas Goirand]

Testing Pike in Sid outputs the below result when doing "openstack --debug console log show 92847293-3b4d-44cc-8cdd-6cb57e23b0cf":

IMO, the issue is that we should be setting the console to output utf8 with something like this:

sys.stdout = codecs.getwriter('utf8')(sys.stdout)

which is what I'm going to do as a patch proposal right away...

nova-console has the same type of problem which I reported separately:

    Fix crashing "console log show"

    Because of encoding issue, the "openstack console show log" is prone to
    a stack dump, as explained in the bug report.

    Use the stdout handle that has already been set up by cliff's App class
    with a sane default encoding.
