API-3: [feat. request]: Operational Data -- Rewards Cycle Time & Harvest Time on Setts

[benefacto]

Description

Request from @BenLeibig
"It would also be nice if you could include information around:

Rewards Cycle Time
Harvest Time on setts (harvest is for all setts per chain I think)

These are other operational data our community cares about. Maybe this doesn't fit well into changes in the API, but if you can easily build in metrics points/health checks that would be nice.

Cycles should occur every 2 hours but is sometimes late, more than 4-6 hours is bad/go red.
BSC harvests should occur ever 2 hours
ETH harvests should occur every 24 hours
These numbers should be dynamic.

This is a suggestion not a requirement."

UI implementation still TBD -- @benefacto

@cedricwaxwing Probably needs UI design for the Setts page

I've done a little noodling on this, and we're in a bit of a tricky spot for the design. I've created the most condensed version possible in this quick local edit:

But, as you can see, it appears our rows can't really handle any additional information. We may want to consider putting a pin in this initiative until we hash out a better solution for displaying the Sett Vaults. For reference, here's a rough sketch/prototype of what I have been playing around with:
