https://github.com/quay/clair/pull/1320 this PR introduced the concept of limiting the number of concurrent requests that Clair is handling. Right now a user can either turn it off or set a number, it would be nice to introduce a 3rd option where the user can specify a value that tells Clair to dynamically calculate the number based on GOMAXPROCS (and possibly other values).

Possible config example:
< 0 == no limit
0 == dynamically assigned limit
> 0 == a user specified number of concurrent requests
