Traffic Router not honoring offline.

[jpappa200]

When setting an edge from reported to offline Traffic Router will continue to redirect hosts after a snapshot. Setting the host to admin_down will stop the redirects. Going from admin_down to offline will cause a small trickle of redirects about 200 per minute.

To Reproduce:

1. Set a server from REPORTED to OFFLINE
2. Snapshot CrConfig
3. Check PeerStates in TM, the value will now be "" instead of "false".

We should also not let Traffic Router route to a server when it is in this state.

Because OFFLINE hosts drop out of the cr-config, we should check for hosts that drop out in general. For example, this could potentially happen when a host is set to REPORTED and then deleted from Traffic Ops. State-wise it would transition from REPORTED to "missing" from the cr-config, which in effect is the same as going from REPORTED to OFFLINE.

I tried to reproduce in Traffic Router with both 1.5.x and master and could not. There must have been something else that happened that caused this issue to happen.
There is still an issue in Traffic Monitor, so I will fix that.

Closing this issue as I could not reproduce.
