> This JIRA is to implement a standalone program that can be used to do "canary monitoring"
of a running HBase cluster. This program would gather a list of the regions in the cluster,
then iterate over them doing lightweight operations (eg short scans) to provide metrics about
latency as well as alert on availability issues.
