Guanghao Zhang 00f2b18148 HBASE-19007 Align Services Interfaces in Master and RegionServer
Purges Server, MasterServices, and RegionServerServices from
CoprocessorEnvironments. Replaces removed functionality with
a set of carefully curated methods on the *CoprocessorEnvironment
implementations (Varies by CoprocessorEnvironment in that the
MasterCoprocessorEnvironment has Master-type facility exposed,
and so on).

A few core Coprocessors that should long ago have been converted
to be integral, violate their context; e.g. a RegionCoprocessor
wants free access to a hosting RegionServer (which may or may not
be present). Rather than let these violators make us corrupte the
CP API, instead, we've made up a hacky system that allows core
Coprocessors access to internals. A new CoreCoprocessor Annotation
has been introduced. When loading Coprocessors, if the instance is
annotated CoreCoprocessor, we pass it an Environment that has been
padded w/ extra-stuff. On invocation, CoreCoprocessors know how to
route their way to these extras in their environment.

See the *CoprocessoHost for how the do the check for CoreCoprocessor
and pass a fatter *Coprocessor, one that allows getting of either
a RegionServerService or MasterService out of the environment
via Marker Interfaces.

Removed org.apache.hadoop.hbase.regionserver.CoprocessorRegionServerServices

M hbase-endpoint/src/main/java/org/apache/hadoop/hbase/security/access/SecureBulkLoadEndpoint.java
 This Endpoint has been deprecated because its functionality has been
 moved to core. Marking it a CoreCoprocessor in the meantime to
 minimize change.

M hbase-rsgroup/src/main/java/org/apache/hadoop/hbase/rsgroup/RSGroupAdminEndpoint.java
 This should be integral to hbase. Meantime, marking it CoreCoprocessor.

M hbase-server/src/main/java/org/apache/hadoop/hbase/Server.java
 Added doc on where it is used and added back a few methods we'd
removed.

A hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/CoreCoprocessor.java
 New annotation for core hbase coprocessors. They get richer environment
 on coprocessor loading.

A hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/HasMasterServices.java
A hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/HasRegionServerServices.java
 Marker Interface to access extras if present.

M hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/MasterCoprocessorEnvironment.java
  Purge MasterServices access. Allow CPs a Connection.

M hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/RegionCoprocessorEnvironment.java
  Purge RegionServerServices access. Allow CPs a Connection.

M hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/RegionServerCoprocessorEnvironment.java
  Purge MasterServices access. Allow CPs a Connection.

M hbase-server/src/main/java/org/apache/hadoop/hbase/quotas/MasterSpaceQuotaObserver.java
M hbase-server/src/main/java/org/apache/hadoop/hbase/quotas/QuotaCache.java
  We no longer have access to MasterServices. Don't need it actually.
  Use short-circuiting Admin instead.

D hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/CoprocessorRegionServerServices.java
  Removed. Not needed now we do CP Env differently.

M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegionServer.java
  No need to go via RSS to getOnlineTables; just use HRS.

And so on. Adds tests to ensure we can only get at extra info
if the CP has been properly marked.
