Error creating user with unicode username

[Liang Chen]

Creating user with unicode username will produce 500.

Here is the culprit in keystone/common/sql/core.py,

     73 if isinstance(column.type, String):
     74 if column.type.length and \
     75 column.type.length < len(str(v)):

It tries to construct a byte string object when testing the length of the string field (username in this case).
This will cause error if the string field ( v ) is a unicode object.

    Fixed unicode username user creation error

    The code tries to construct a byte string object to test the
    length of the string field (The explicit construction of the
    string object is neccessary as sometime v can be other types,
    for example int). This will cause error if the string field
    (v) is a unicode object.

    Fixes bug #1166701
