Summary: This test subclasses the BigLinkedList test. It takes two hbase clusters as arguments, sets up tables, sets up replication, and runs the BigLinkedList generator. The verification portion of the loop checks that the sink of the replication has the data and it is correct.
Test Plan: ran the test on my laptop and a small live cluster

Use the context passed back via ScanResponse that a RegionServer
fills in to denote whether or not more results existing in the
current Region. Add a simple factory to remove a static method
used across both SmallScanner and SmallReverseScanner. Add new
unit tests for both scanner classes to test scans with and
without the new context (as a quick backward-compatibility test).
The RS already returns to the client whether or not it has additional
results to be returned in a subsequent call to scan(), but the ClientScanner
did not use or adhere to this value. Subsequently, this can lead to
bugs around moving to the next region too early. A new method was added
to ClientScanner in the name of testability.
Encapsulate server-state into RegionServerCallable to avoid
modifying parameterization of callable impls.

Summary:
The current behavior of a region move shuts down a region and then starts is up in another regionserver. This causes increased latency and possibly timeouts till the new region's cache is fully warmed up. We can make a region move less disruptive by warming the cache in the destination region server before shutting dow the old region.
See https://issues.apache.org/jira/browse/HBASE-13316
Test Plan:
1. Unit Tests
2. Added test for concurrent moves and warmups
3. Manually tested reads/writes happening with concurrent moves
