Ceilemeter command will occur a UnicodeEncodeError when using LANGUAGE=ja_JP.UTF-8

[xiaoc]

In ceilometer/api/controllers/v2.py ,can see

    if len(alarms) < 1:
            raise wsme.exc.ClientSideError(_("Unknown alarm"))

using ceilometer/api/controllers/v2.py, generat a pot file to ceilometer/locale, then copy its content to ceilometer/locale/ja/LC_MESSAGES/ceilometer.po, then modify the po file.

In po file "Unknown alarm" value is a Japanese word.

Then,

msgfmt -o ceilometer/locale/ja/LC_MESSAGES/ceilometer.mo ceilometer/locale/ja/LC_MESSAGES/ceilometer.po

use LANGUAGE=ja_JP.UTF-8, CEILOMETER_LOCALEDIR=ceilometer/locale.

now execute the command:

ceilometer -d alarm-delete -a -

will get the error:

    Use wsme ClientSideError to handle unicode string

    We inherit from wsme.esc.ClientSideError to handle unicode string in
    error message.

    Refactor API error handling

    Refactor the API error handling to ensure error messages are translated.
    Since wsme 0.5b6, the error message doesn't need to be converted to
    unicode, wsme handles it for us.
