Update to support newer versions of django-redis #2
Description
Hi, seems current version is incompatible with newest versions of django-redis.
Currently getting the following error when trying to write to redis:
File "/srv/metax/pyenv/lib/python3.5/site-packages/django_redis/client/default.py", line 123, in set
client, index = self.get_client(write=True, tried=tried, show_index=True)
TypeError: get_client() got an unexpected keyword argument 'tried'
After fixing the parameters in django_redis_sentinel/client/sentinel.py get_client(), more errors follow:

Software versions:
redis-server 2:3.0.6-1
Django==1.11.1
django-redis==4.8.0
django-redis-sentinel-redux==0.2.0
I have verified using redis-cli that the redis instances and sentinels are correctly configured, and failover is otherwise working.
