Allow sst partitioner methods to be mutable. On RocksDB side these methods are not const methods, thus should be mutable.

Expose dictionary compression options for rocksdb to Tikv. So we could introduce dictionary compression to Tikv to relieve the compression issue. It's part of work [Issue 8635](https://github.com/tikv/tikv/issues/8635).

### Summary
Integration with rockset/rocksdb-cloud to add CloudEnv features for operating with cloud services like AWS S3 as a datastore.
- Created a sub-crate `librocksdb_cloud_sys` which contains the `rocksdb-cloud` sub-module containing code for managing cloud interactions, extracted from rockset/rocksdb-cloud and currently residing in [tikv/rocksdb~6.4.cloud](https://github.com/tikv/rocksdb/tree/6.4.cloud)
- Made necessary changes to [tikv/rocksdb~6.4.tikv](https://github.com/tikv/rocksdb/tree/6.4.tikv) that is housed in the sub-module `rocksdb` within the parent crate.
- Wrote CMakeLists.txt for use in the build process of `rocksdb_cloud` as a static library, usable for C-ABI based FFI calls. Added the above code to the build process of parent crate `librocksdb_sys` along with C-ABI binding code within `crocksdb`
- Created 'cloud.rs' and added `new_aws_env()` method to Env type of `rocksdb.rs` that merely makes a call to the `CloudEnv::NewAwsEnv()` via FFI for use as library features upstream. A test for the same was also added here.
- Used feature based conditional compile macros to all cloud interaction code.
- Made requisite changes to CI config for handling AWS SDK compilation.
- Added a sequence of steps to update submodule within Makefile

Solves #514

## Checkpoints

- [x] Added rocksdb-cloud as submodule in crate `librocksdb_cloud_sys`.
- [x] Write CMakeLists.txt to build only `cloud` code.
- [x] Generate C-bindings to interface with `NewAwsEnv` and `CloudEnvOptions`
- [x] Create `Env::new_aws_env` as an interface in rust

* RocksDB may print large log lines up to 64k. The default 1k buffer for `logv` is too small and truncates rocksdb log. When we detect log line is too long, we allocate a large enough buffer on heap and try again.
* When log level is not specified, defaults to header level.
