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.
