add update and reval flag to indicate failure

[jpappa200]

This Feature Request affects these Traffic Control components:

• Traffic Control Cache Config (t3c, formerly ORT)
• Traffic Ops
• Traffic Portal

Description

Right now in TC we have a checkmark to indicate caches are up to date and/or update has succeeded. We have a clock to signal a cache has a pending update. I would like to add an X flag to indicate an update failure. We really don't have any way to indicate a failure unless we're watching the t3c logs. A lot of times t3c will clear the update flag on failure otherwise every 3 min (or what ever update interval is set) t3c will pull the configs and do a full run and fail repeatedly until the issue is fixed. On failure I would like t3c to set the update failed flag X in TO as an indication a failure has occurred and should be investigated. Also t3c will not consider the X as a pending update, and once the server is fixed updates could be queued again to signal an update is pending.
