Add local tensor-parallel fwd/bwd (#143) 
This pull request adds an option to run Petals server on multiple local GPUs. It uses https://github.com/BlackSamorez/tensor_parallel

- 8bit approximation error same as in main (mean~=2% q0.9~=5%)
    - TP=1, 2, 3 (see screenshots above)
- forward, grad w.r.t. input and inference exact match with main with TP=1
- `>=`80% GPU utilization with 3x 1080ti, batch = 8 tokens
- throughput measured with and without TP
- TP on 1080Tis has near-linear speedup comparable to the benchmarks (see first message)

Make Petals a pip-installable package (attempt 2) (#102) 
1. Petals can be now installed using `pip install git+https://github.com/bigscience-workshop/petals`
    - In case if you already cloned the repo, you can do `pip install .` or `pip install .[dev]`
2. Moved `src` => `src/petals`
    - Replaced `from src.smth import smth` with `from petals.smth import smth`
3. Moved `cli` => `src/petals/cli`
    - Replaced `python -m cli.run_smth` with `python -m petals.cli.run_smth` (all utilities are now available right after pip installation)
4. Moved the `requirements*.txt` contents to `setup.cfg` (`requirements.txt` for packages is not supported well by modern packaging utils)
5. Increased the package version from `0.2` to `1.0alpha1`

Let users specify sequence length instead of assuming 2048 (#52) 
- Maximum length is now provided in `.inference_session(max_length=100)`
   - previously, we would always assume max length = 2048
- added a generic way to forward **kwargs to inference session
  - for compatibility with #47 
  - Note to @borzunov : it does *not* pass them arbitrarily, but instead checks for kwarg names at the bottom level
- run_server can be started with a custom max_length for inference
- renamed --cache_size_bytes to --attention_cache_bytes (to avoid collision with --cache_dir)
- --attn_cache_bytes can now support humane file sizes (e.g. 300MB instead of 314572800)
- made some server-side errors more human-readable to user (e.g. when max length is exceeded)

Implement RemoteSequential slicing and extra repr, add tests (#30) 
- finish renaming RemoteSequenceInfo -> RemoteSequenceManager (why: if it was an *Info, user would expect it to be similar - to a dataclass; whereas in actuality, the class is doing heavy network interactions on its own)
- implement RemoteSequenceManager.make_sequence (from https://pastebin.com/uXgy2U8B )
- make RemoteSequentialInferenceSession use RemoteSequenceManager.make_sequence
- make tests pass again
- make it possible to create inference session without RemoteTransformerBlock
- make a standalone test for RemoteSequential
- rollback convert-model

Add automated tests (#23) 
This PR will run basic tests automatically on each subsequent PR

- convert a small model on every PR
- run existing tests on every PR
- enforce black / isort
- require checks on merge
- make sure tests are not flappy
