riemann-redis run_id can be infinity

[gsandie]

Riemann-redis will convert the redis run_id to a float, this can come out as Infinity in ruby.

The run_id is a "Random value identifying the Redis server (to be used by Sentinel and Cluster)".

Rather than change the value to a float, I'd like to set it to nil or 0 as I think that more accurately reflects the run_id (the actual value will still be saved in the description).

Anyone using this value as a metric? Happy for this change?

I should also say, the infinity value causes exceptions in riemann:

Yeah, I think that's a good decision, Gavin.
