add dropwizard metrics

[kortemik]

add at least following:

• [ ] total counters for runtime, provides visibility to instance over all utilization
  • [x] total records
  • [x] total bytes
  • [ ] total k8s api calls
  • [x] second since startup (uptime)
  • [ ] total active containers
  • [x] total active connections
  • [x] total reconnects
  • [x] total errors in processing
  • [ ] configured api cache duration
  • [ ] total label configuration missing containers, increment always when api call does not have proper labels
  • [ ] total records sent with default labels
• [x] total throughput, provides visibility, provides visibility to instance current utilization
  • [x] record per second (rps)
  • [x] bytes per second (bps)
• [ ] total combined latency, provides visibility to target system performance
  • [ ] connect latency
  • [ ] send latency
  • [ ] k8s api call latency
  • [ ] k8s api cache latency
  • [ ] file parsing latency

add following per podName metrics, provides detailed visibility to :

• [ ] podName total counters
  • [ ] records
  • [ ] bytes
  • [ ] second since startup (pod logger uptime)
  • [ ] reconnects
  • [ ] errors
  • [ ] api calls without proper labels
  • [ ] records sent with default labels
• [ ] podName throughput
  • [ ] record per second (rps)
  • [ ] bytes per second (bps)
• [ ] podName latency
  • [ ] connect latency
  • [ ] send latency
  • [ ] file parsing latency
  • [ ] k8s api call latency
  • [ ] k8s api cache latency

Pr #24 adds some of the metrics

[kortemik]

not all added?
