Nawaz Dhandala f49b1995df feat(telemetry): add new Telemetry service (OTel, Syslog, Fluent, Metrics, Traces) and unified ingestion pipeline
- Add Telemetry service entrypoint
  - Telemetry/Index.ts: app bootstrap, routes mounting, infrastructure init and Telemetry SDK init.

- Unified queue + worker
  - Telemetry/Jobs/TelemetryIngest/ProcessTelemetry.ts: single worker that dispatches queued jobs to specific processors (logs, traces, metrics, syslog, fluent logs).
  - Telemetry/Services/Queue/TelemetryQueueService.ts: central queue API and job payload types.
  - Per-type Queue wrappers (LogsQueueService, MetricsQueueService, TracesQueueService, FluentLogsQueueService, SyslogQueueService).

- OpenTelemetry ingestion middleware and proto support
  - Telemetry/Middleware/OtelRequestMiddleware.ts: detect OTLP endpoint (logs/traces/metrics), decode protobuf bodies using protobufjs and set product type.
  - Telemetry/ProtoFiles/OTel/v1/*.proto: include common.proto, logs.proto, metrics.proto, resource.proto, traces.proto for OTLP v1 messages.

- Ingest services
  - Telemetry/Services/OtelLogsIngestService.ts: parse incoming OTLP logs, map attributes, convert timestamps, batch insert logs.
  - Telemetry/Services/OtelTracesIngestService.ts: parse OTLP traces, build span rows, extract exceptions, batch insert spans and exceptions, save telemetry exception summary.
  - Telemetry/Services/OtelMetricsIngestService.ts: parse OTLP metrics, normalize datapoints, batch insert metrics and index metric name -> service map.
  - Telemetry/Services/SyslogIngestService.ts: syslog ingestion endpoints, parser integration, map syslog fields to attributes and logs.
  - Telemetry/Services/FluentLogsIngestService.ts: ingest Fluentd style logs, normalize entries and insert into log backend.
  - Telemetry/Services/OtelIngestBaseService.ts: helpers to resolve service name from attributes/headers.

- Syslog parser and utilities
  - Telemetry/Utils/SyslogParser.ts: robust RFC5424 and RFC3164 parser, structured data extraction and sanitization.
  - Telemetry/Tests/Utils/SyslogParser.test.ts: unit tests for parser behavior.

- Telemetry exception utilities
  - Telemetry/Utils/Exception.ts: generate exception fingerprint and upsert telemetry exception status (saveOrUpdateTelemetryException).

- Queue & job integration
  - New integration with Common/Server/Infrastructure/Queue and QueueWorker, job id generation and telemetry job types.
  - Telemetry services add ingestion jobs instead of processing synchronously.

- Config, build and dev tooling
  - Add Telemetry/package.json, package-lock.json, tsconfig.json, nodemon.json, jest config.
  - New script configs and dependencies (protobufjs, ts-node, jest, nodemon, etc).

- Docker / environment updates
  - docker-compose.base.yml, docker-compose.dev.yml, docker-compose.yml: rename service from open-telemetry-ingest -> telemetry and wire TELEMETRY_* envs.
  - config.example.env: rename and consolidate environment variables (OPEN_TELEMETRY_* -> TELEMETRY_*, update hostnames and ports).
  - Tests/Scripts/status-check.sh: update ready-check target to telemetry/status/ready.

- Other
  - Telemetry/Services/Queue/*: export helpers and legacy-compatible job interface shims.
  - Memory cleanup and batching safeguards across ingest services.
  - Logging and capture spans added to key code paths.

BREAKING CHANGES / MIGRATION NOTES:
- Environment variables and docker service names changed:
  - Replace OPEN_TELEMETRY_... vars with TELEMETRY_... (PORT, HOSTNAME, CONCURRENCY, DISABLE_TELEMETRY, etc).
  - docker-compose entries moved from "open-telemetry-ingest" to "telemetry" and image name changed to oneuptime/telemetry.
  - Update any deployment automation and monitoring checks referencing the old service name or endpoints.
- Consumers: OTLP endpoints and behavior remain supported, but ingestion is now queued and processed asynchronously.

Testing / Running:
- Install deps in Telemetry/ (npm install) after syncing Common workspace.
- Run dev: npx nodemon (nodemon.json) or build & start using provided scripts.
- Run tests with jest (Telemetry test suite includes SyslogParser unit tests).

Files added/modified (high level):
- Added many files under Telemetry/: Index, Jobs, Middleware, ProtoFiles, Services, Utils, Tests, package and config artifacts.
- Modified docker-compose.* and config.example.env and status check script to use new TELEMETRY service/vars.

Syslog Testing Instructions

Test in terminal, send a sample RFC5424 payload:

curl -X POST \
  -H "Content-Type: text/plain" \
    -H "x-oneuptime-token: YOUR_TEST_TOKEN" \
    -H "x-oneuptime-service-name: local-syslog" \
  --data '<134>1 2024-07-10T17:25:43.123Z host app 1234 ID47 [exampleSDID@32473 iut="3" eventSource="App"] An application event log entry' \
  https://oneuptime.com/syslog/v1/logs

Replace YOUR_TEST_TOKEN and local-syslog with a valid telemetry key and desired service label. Please also replace oneuptime.com with your host if you're testing this locally.

Inspect the service logs or connected queue to ensure the message is accepted and parsed.
