feat!: gather telemetry

[0x009922]

TODO:

• Implement actual gathering in peer_monitor
• Implement blockchain data collection
• OpenAPI specs
• Merge feat: add commit time metrics hyperledger-iroha/iroha#5380 and reference updated Iroha in Cargo.toml.

Overview

• Accepts list or Torii URLs in the configuration
• Continuously gather various information for each peer:
  • Its configuration
  • Its online peers
  • Its high-level metrics (requires telemetry feature in irohad)
  • Its geographical location by querying the host name of the peer URL to http://ip-api.com
• Provide information such as status connection and telemetry support by the peer
• Serve telemetry via oneshot requests or via a live-stream as updates are available
• Improve and organise OpenAPI docs

Caveats:

• Does not support dynamic peers updates
• Does not support automatic peers discovery (see Gossip public Torii URLs to help with automatic discovery hyperledger-iroha/iroha#5367)

API Changes

• Removed GET /status
• Added GET /telemetry/network for network metrics
• Added GET /telemetry/peers for peers metrics (frequently updated)
• Added GET /telemetry/peers-info for peers info (less frequently updated)
• Added GET /telemetry/live for live updates of all abovementioned data via Server-Sent Events

Config Changes

Renamed --torii-url (IROHA_EXPLORER_TORII_URL) to --torii-urls (IROHA_EXPLORER_TORII_URLS) (urls) for comma-separated URLs of peers.
