rdhabalia and sijie clear old function failure exception from stats (#2632)
### Motivation

Right now, if function fails first time and then starts and runs successfully then still function-stats shows old exception in stats which confuses user regarding function current state.

### Modifications

Hide old exception if function started successfully.

  • Topic and queue semantics
  • Load balancer
  • Designed for being deployed as a hosted service:
    • Multi-tenant
    • Authentication
    • Authorization
    • Quotas
    • Support mixing very different workloads
    • Optional hardware isolation
  • Keeps track of consumer cursor position
  • REST API for provisioning, admin and stats
  • Geo replication
  • Transparent handling of partitioned topics
  • Transparent batching of messages
