* Add paramter to loadstatus API to compute underdeplication against cluster view
This change adds a query parameter `computeUsingClusterView` to loadstatus apis
that if specified have the coordinator compute undereplication for segments based
on the number of services available within cluster that the segment can be replicated
on, instead of the configured replication count configured in load rule. A default
load rule is created in all clusters that specified that all segments should be
replicated 2 times. As replicas are forced to be on separate nodes in the cluster,
this causes the loadstatus api to report that there are under-replicated segments
when there is only 1 data server in the cluster. In this case, calling loadstatus
api without this new query parameter will always result in a response indicating
under-replication of segments

* Improve Druid ldap auth documentation
Improved the ldap auth docs by clarifying that the object classes and
attributes noted are specific to Microsoft Active Directory, and could
be different depending on the specific ldap server being used. Also
emphasized the importance of the memberOf field and noted that the
step about adding users to roles is only needed in certain circumstances.

* dynamic coord config adding more balancing control
add new dynamic coordinator config, maxSegmentsToConsiderPerMove. This
config caps the number of segments that are iterated over when selecting
a segment to move. The default value combined with current balancing
strategies will still iterate over all provided segments. However,
setting this value to something > 0 will cap the number of segments
visited. This could make sense in cases where a cluster has a very large
number of segments and the admins prefer less iterations vs a thorough
consideration of all segments provided.
