cisco-roam: Add notes and fix setting bgscan.
Added notes on things to improve, especially scan/sleep logic, and at lower priority, fix hard-coded resource-1 instances. I moved bgscan setting to before STA are brought up so that changes will be applied when STA comes up. Code is untested, please review the TODO notes, fix those up, and re-test.
