Matthew Jacobs 54de8d1d92 IMPALA-1565: Python sasl client transport perf issue ...

The shell uses the thrift sasl client (thrift_sasl.py) for communication with
impalads when using ldap and/or kerberos. The sasl client currently makes calls
into sasl for every buffer repeatedly even when it is not necessary, resulting
in a significant performance degradation when using the impala-shell w/ kerberos
and/or ldap.

thrift_sasl.py was forked from hue at some point, and this change updates the
code to reflect the updated code as of hue commit a9898b4e815b3ec9918c5db65e0d9bd1d0ecdde0
which only calls into sasl when frames are encoded.
