cqlsh describe fails with "list[i] not a string for i in..."

      Description

      repro:
      Create a keyspace and a few user types.

      use keyspace;
      desc types;
      

      This is caused by a limitation in cmd.Cmd.columnize in that it doesn't accept unicode, which our identifiers are. Ending stack trace:

      "...bin/cqlsh.py", ... in describe_usertypes
          cmd.Cmd.columnize(self, protect_names(ksmeta.user_types.keys()))
        File "/Users/adamholmberg/.pyenv/versions/2.7.8/lib/python2.7/cmd.py", line 363, in columnize
          ", ".join(map(str, nonstrings)))
      TypeError: list[i] not a string for i in 0, 1, 2, 3, 4
      

      This was previously obscured because the driver was incorrectly encoding identifiers in protect_name, which caused other problems for cqlsh schema generation. With that change, we now must encode identifiers in cqlsh to avoid blowing up columnize.
