Move warning messages from DEBUG to WARN

Move debug messages from DEBUG to WARN

Some log messages should be showed as warnings and not as DEBUG
messages.

Fix zrank() return type capture

Use object form of Long for zrank() return type

The Jedis docs for each command are just a copy paste of Redis docs
which doesn't translate well to Java.
https://github.com/xetorthio/jedis/issues/978

From some stack overflow googling, we see the right way to use
zrank(), and this patch changes the code to comply with that.

Clearer debug message for popMsgWithId()

v2.0.11-rc3

Make debug message clearer in popWithMsgId()

Clearer debug message for popMsgWithId()

Add unsafePopWithMsgIdAllShards() API

Similar to popWithMsgId(), but attempts to pop from any shard.
Hence, prefixed with unsafe.

Testing: Added a test to the DynoQueueDemo.

New APIs; New ShardSupplier; Bug fixes

• Add a new ShardSupplier to address issues with DynoShardSupplier
• Allow containsPredicate()/getMsgWithPredicate() to filter on local shard
• Add unsafePopWithMsgIdAllShards() API
• unsafePopAllShards() should use the prefetched IDs from the unsafe Map (to pop from local shard first)

Expose unsafe functions and fix process unacks

Add unsafePeekAllShards() and unsafePopAllShards() functions

This patch exposes 2 new APIs that allow the calling application to
peek into and pop from all shards of the queue.

The APIs are prepended with unsafe* because if multiple client app
instances call these APIs concurrently, it's possible that duplicate
items may be returned to the application across client instances. Hence,
these APIs must not be used unless the calling application's use case
is okay with handling duplicate items.

The DynoQueueDemo is updated to use these new APIs.

Additionally, a lot of the code is refactored in V1.

Misc fixes

• processUnacks() should use nonQuorumConn to look over a range in the zset
• Make peekIds() use nonQuorumConn.
• Add logging for processUnacks()

New queue APIs and bug fixes

• New API: popWithMsgId().
• containsPredicate() and getMsgWithPredicate() use Lua pattern matching now.
• Fixed remove() from returning incorrect return value in some cases.
• More tests added to V1 demo

Update dyno dependency to dyno-1.7.1

Update APIs to compile with dyno-1.7.1

- All Host() objects are changed to be created with a HostBuilder.
- Slight Demo API change

Improved logging for processUnacks() and make peekIds() non quorum based

v2.0.0-rc9

Pin to dyno-1.6.5-rc.4
