SocketMemcachedTests seems to be redundant

[moisesguimaraes]

The test SocketMemcachedTests seems redundant in the current codebase.

python-binary-memcached/test/test_socket.py

Lines 5 to 12 in a2d718f

	class SocketMemcachedTests(test_simple_functions.MemcachedTests):
	"""
	Same tests as above, just make sure it works with sockets.
	"""
	def setUp(self):
	self.server = '/tmp/memcached.sock'
	self.client = bmemcached.Client(self.server, 'user', 'password')

It extends test_simple_functions.MemcachedTests, but this one is also a socket test:

python-binary-memcached/test/test_simple_functions.py

Lines 17 to 21 in a2d718f

	class MemcachedTests(unittest.TestCase):
	def setUp(self):
	self.server = '/tmp/memcached.sock'
	self.client = bmemcached.Client(self.server, 'user', 'password')
	self.reset()
