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)

Shield alloc & free from cancellation (#163) 
A handler's RPC code may be cancelled due to a request timeout or a client closing the connection. Before this PR:

- If `.cancel()` happens while waiting for `hivemind.utils.enter_asynchronously()`, the lock will never be released.
- If `.cancel()` happens while doing that before freeing memory, the memory will never be freed.

This PR fixes it by deferring the cancellation with [asyncio.shield()](https://docs.python.org/3/library/asyncio-task.html#asyncio.shield). Now, the cancellation will happen only when all locks are released and alloc/free has completed.

Reset MemoryCache during rebalancings (#154) 
Before this PR, if there were open inference sessions right when rebalancing is triggered, their cache was never properly destroyed.
