Replace .make_sequence(..., mode="random") with mode="max_throughput" (#313) 
We need to sample the next server using its throughput as the weight to actually achieve max throughput for fine-tuning.

As an example, imagine a situation where we have 3 servers with throughputs [1000, 500, 1] hosting the same blocks, then compare the uniform and weighted sampling strategies.

Merge inference pools into one to increase inference speed (#225) 
It turns out using a separate pool for each block has led to significant slowdown, see #224 for details.

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`
