[rahulbandariSensei]

The purpose and use-cases of the new component

Apache Druid Receiver(apachedruid) listens on for the metrics emitted by the apache druid endpoint as mentioned in metrics page and generates all the metrics related to different sub-components of a druid cluster.

Example configuration for the component

receivers:
   apachedruid:
    emitterport: 8911

Telemetry data types supported

Metrics Emitted by the apache druid (https://druid.apache.org/docs/latest/operations/metrics.html) would be supported here.
Will update the names shortly.
