Addresses review comments by Sean Busbey and Appy that happened
to come in long after the commit of HBASE-6721, the original
rsgroup issue.
Also includes subsequent accommodation of Duo Zhang review.
Adds a new type to hold hostname and port. It is called
Address. It is a facade over Guava's HostAndPort. Replace
all instances of HostAndPort with Address. In particular,
those places where HostAndPort was part of the rsgroup
public API.
Fix licenses. Add audience annotations.
Cleanup and note concurrency expectation on a few core classes.
In particular, all access on RSGroupInfoManager is made
synchronized.
M hbase-client/src/main/java/org/apache/hadoop/hbase/ServerName.java
Host the hostname and port in an instance of the new type Address.
Add a bunch of deprecation of exotic string parses that should never
have been public.
M hbase-rsgroup/src/main/java/org/apache/hadoop/hbase/rsgroup/RSGroupAdmin.java
Make this an Interface rather than abstract class. Creation was a
static internal method that only chose one type.... Let it be free
as a true Interface instead.
Renamed move_rsgroup_servers as move_servers_rsgroup
Renamed move_rsgroup_tables as move_tables_rsgroup
Minor changes to help text in rsgroup commands making them all same.
Made LOG from RSGroupAdminServer all talk of 'rsgroup' rather than
'group' to be consistent.
Fix for table.jsp where it would fail to display regions because no
type for the protobuf record specified.
Fix it so that move of an offline server to 'default' rsgroup is like
moving the reference to the server to trash (keeps the 'default' group
consistently 'dynamic' regards its server-list).
Fixed another issue where we were stuck in a loop because regions
were in FAILED_OPEN state because no server to assign too so we'd
never recover (a vagary of the current state of Master assignement
but no less a possibility in real world deploys).
Make it so servers are sorted when we list them; its what operator
would expect.
Support weekly and monthly mob compact partition policies in addition to the existing
daily partition policy.

- Testing by executing a command will cover the exact path users will trigger, so its better then directly calling library functions in tests. Changing the tests to use @shell.command(:<command>, args) to execute them like it's a command coming from shell.
Norm change:
Commands should print the output user would like to see, but in the end, should also return the relevant value. This way:
- Tests can use returned value to check that functionality works
- Tests can capture stdout to assert particular kind of output user should see.
- We do not print the return value in interactive mode and keep the output clean. See Shell.command() function.
Bugs found due to this change:
- Uncovered bug in major_compact.rb with this approach. It was calling admin.majorCompact() which doesn't exist but our tests didn't catch it since they directly tested admin.major_compact()
- Enabled TestReplicationShell. If it's bad, flaky infra will take care of it.

Functions format_simple_command and format_and_return_simple_command are used to print runtimes right now. They are called from within every single command and use Ruby's 'yield' magic. Instead, we can simplify it using 'command_safe' function. Since command_safe wraps all commands, we can simply time before and after we call individual command.
If a command only wants to time a part of its logic, it can set instance variables start_time and end_time accordingly which is far more simpler to understand and work with than 'yield'.

- Renaming hbase.rb to hbase_constants.rb because there are two hbase.rb files right now which is confusing.
- Remove omnipresence of formatter object since it is kind of a use-and-throw class. Commands should create
an instance, use it to format the output and discard it.
- Some refactoring
