redis 3.3.0 adds `Connection.health_check_interval` attribute

[isms]

An attribute added to redis.connection.Connection last week in 3.3.0 causes an error with current FakeConnection since this attr is now expected.

Here is an example traceback from rq up through redis (with redis==3.3.0 and fakeredis==1.0.3):

Thanks for the report. I'm going on holiday shortly so I won't be able to deal with this for a few weeks. I'll try to remember to look at it when I get back. If you haven't heard anything by late August feel free to ping me again.

Hi @bmerry, do you plan to release this fix soon?

I'm on holiday at the moment, but I should be able to get a release out later this week.
