Previously `Ray.createActor` only support creating an actor without any parameter. This PR adds the support for creating an actor with parameters. Moreover, besides using a constructor, it's now also allowed to create an actor with a factory method. For more usage, prefer refer to `ActorTest.java`.
API module (`ray/java/api` dir) includes all public APIs provided by Ray, it should be the only module that normal Ray users need to face.
The purpose of this PR to first improve the code quality of the API module. Subsequent PRs will improve other modules later. The changes of this PR include the following aspects:
1) Only keep interfaces in api module, to hide implementation details from users and fix circular dependencies among modules.
2) Document everything in the api module.
3) Improve naming.
4) Add more tests for API.
5) Also fix/improve related code in other modules.
6) Remove some unused code.
(Apologize for posting such a large PR. Java worker code has been lack of maintenance for a while. There're a lot of code quality issues that need to be fixed. We plan to use a couple of large PRs to address them. After that, future changes will come in small PRs.)

Basically a re-implementation of #2281, with modifications of #2298 (A fix of #2334, for rebasing issues.).
[+] Implement sharding for gcs tables.
[+] Keep ClientTable and ErrorTable managed by the primary_shard. TaskTable is managed by the primary_shard for now, until a good hashing for tasks is implemented.
[+] Move AsyncGcsClient's initialization into Connect function.
[-] Move GetRedisShard and bool sharding from RedisContext's connect into AsyncGcsClient. This may make the interface cleaner.

1) Renamed the native JNI methods and some parameters of JNI methods.
2) Fixed native JNI methods' signatures by `javah` tool.
3) Removed some useless native methods.
This removes the force_start argument from StartWorkerProcess in the worker pool so that no more than maximum_startup_concurrency are ever started concurrently. In particular, when the raylet starts up, it my start fewer than num_workers workers.

## What do these changes do?
* distribute load and resource information on a heartbeat
* for each raylet, maintain total and available resource capacity as well as measure of current load
* this PR introduces a new notion of load, defined as a sum of all resource demand induced by queued ready tasks on the local raylet. This provides a heterogeneity-aware measure of load that supersedes legacy Ray's task count as a proxy for load.
* modify the scheduling policy to perform *capacity-based*, *load-aware*, *optimistically concurrent* resource allocation
* perform task spillover to the heartbeating node in response to a heartbeat, implementing heterogeneity-aware late-binding/work-stealing.

## What do these changes do?
Because the logic of generating `TaskID` in java is different from python's, there are many tests fail when we change the `Ray Core` code.
In this change, I rewrote the logic of generating `TaskID` in java which is the same as the python's.
In java, we call the native method `_generateTaskId()` to generate a `TaskID` which is also used in python. We change `computePutId()`'s logic too.

[#2608](https://github.com/ray-project/ray/issues/2608)
This PR enables multi-language support in the raylet backend.
- `Worker` class now has a `language` label;
- `WorkerPool`:
- It now maintains one set of states for each language.
- `PopWorker` function's parameter type is changed to `TaskSpecification`, and it will choose a worker to pop based on both task's language and actor id.
- `Size` and `StartWorkerProcess` functions now have an extra `language` parameter.
- `RegisterClientRequest` message now has an extra `language` field in raylet mode, which tells the node manager which language the worker is.
## What do these changes do?
1. Separate the log related code to logger.py from services.py.
2. Allow users to modify logging formatter in `ray start`.

## What do these changes do?
#2362 left a bug where it assumed that the driver task ID was nil. This fixes the bug to check the `SchedulingQueue` for any driver task IDs instead.
