This patch changes uses of has_key() as suggested by the 2to3 utility.

Note: Fedora packaging guidelines require explicit shebangs, so popular
practices like #!/usr/bin/env python and #!/usr/bin/python are not
allowed; they must be #!/usr/bin/python2 or #!/usr/bin/python3

Note: Selected small fixes from 2to3 utility. Specifically apply,
basestring, funcattrs, idioms, numliterals, set_literal, types, urllib,
zip, map, and raise have already been applied. Also version agnostic
imports for urllib, cpickle, socketserver, _thread, queue, etc., suggested
by Aravinda in https://review.gluster.org/#/c/19767/1

Note: these 2to3 fixes report no changes are necessary: asserts, buffer,
exec, execfile, exitfunc, filter, getcwdu, imports2, input, intern,
itertools, metaclass, methodattrs, ne, next, nonzero, operator, paren,
raw_input, reduce, reload, renames, repr, standarderror, sys_exc, throw,
tuple_params, xreadlines.

Updates: #411
