Gian Merlino 4881bb273b Only consider loaded replicants when computing replication status. (#4921)
* Only consider loaded replicants when computing replication status.

This affects the computation of segment/underReplicated/count and
segment/unavailable/count, as well as the loadstatus?simple and
loadstatus?full APIs.

I'm not sure why they currently consider segments in the load
queues, but it would make more sense to me if they only considered
segments that are actually loaded.

* Fix tests.

* Fix imports.

Druid

Druid is a distributed, column-oriented, real-time analytics data store that is commonly used to power exploratory dashboards in multi-tenant environments.

Druid excels as a data warehousing solution for fast aggregate queries on petabyte sized data sets. Druid supports a variety of flexible filters, exact calculations, approximate algorithms, and other useful calculations.

Druid can load both streaming and batch data and integrates with Samza, Kafka, Storm, Spark, and Hadoop.
