Improvement: Create an aggregate chain status endpoint

[sgerogia]

The front-end needs to get the up-to-date status for all supported chains.

Atm this is called per chain (>20 in PROD) and happens every 5 sec. This results in a lot of overhead (network latency, SSL handshakes,...)

Offer a new endpoint which will provide the info for all chains at once.

DoD

• [ ] New endpoint /chains/status
• [ ] Payload looks like (TBA with front-end team)

  {
  "osmosis": {
  "status": false, // as derived from TL tables
  "enabled": true // as derived from CNS
  }
  }

• [ ] Unit tested
• [ ] demeris-backend int. tests
