health_check_interval is set to True, not number of seconds

[André Roaldseth]

The documentation of redis-py says health_check_interval is an int for the number of seconds between health checks or ping/pong.

 health_check_interval=True, 

I assume setting it to true would be the same as setting it to 1? Maybe 10, 30, or a configurable value would be better?

I'm open to PRs supporting configuration for this setting.

For what it's worth, this health check interval works in production, even if it is a little too frequent
