Tracing is fun

Versions:

• Minimum supported Go version is 1.16
• Bump sentry-go to 0.11.0
• Bump zap to 1.19.1

Changes:

• Add tracing support to HTTP middleware and BreadcrumbTransport
• Enrich Sentry event info with data from HTTP request
• Remove X-Request-Id header from middleware
  • Context helpers still works to avoid code breaking
  • You should use Sentry trace ID instead
• Add support for creating forked logger
  • It's something like what already happening inside HTTP middleware
  • It's a logger with same cores but with new sentry.Hub
  • This is useful when you have request-based system built not on top of HTTP (something like gRPC or else)
