separate warning and crit errors of agents that are disabled|down

[sudeephb]

It's very hard to see which hosts are the troubled hosts when seeing the disabled merged with the down hosts

Sample:

CRITICAL: nova-compute, Host AZ1-Compute-1 disabled, Host AZ1-Compute-2 disabled, Host AZ2-Compute-1 disabled, Host AZ2-Compute-5 disabled, AZ1-Compute-14 down, Host AZ2-Compute-2 disabled, Host AZ1-Compute-6 disabled, Host AZ1-Compute-11 disabled, AZ1-Compute-13 down, Host AZ1-Compute-5 disabled, AZ2-Compute-8 down, Host AZ2-Compute-5 disabled, Host AZ1-Compute-2 disabled, Host AZ2-Compute-2 disabled, Host AZ1-Compute-1 disabled, Host AZ1-Compute-6 disabled, Host AZ1-Compute-11 disabled, Host AZ1-Compute-5 disabled, AZ1-Compute-14 down, AZ1-Compute-13 down

Improvement suggested: CRITICAL: nova-compute Hosts disabled: AZ1-Compute-1, AZ1-Compute-2, AZ2-Compute-1, AZ2-Compute-5, AZ2-Compute-2, AZ1-Compute-6, AZ1-Compute-11, AZ1-Compute-5, AZ2-Compute-5, AZ1-Compute-2, AZ2-Compute-2, AZ1-Compute-1, AZ1-Compute-6, AZ1-Compute-11, AZ1-Compute-5 Hosts down : AZ1-Compute-14, AZ1-Compute-13, AZ2-Compute-8, AZ1-Compute-14, AZ1-Compute-13

(by guoqiao) Maybe we can move even further, to show them in a table with nagios multiple line msg.
