Nuno CamposandGitHub 3b05279e32 Implement serialization with msgpack library (#1716) 
* Implement serialization with msgpack library

- encode custom python objects with a msgpack extension type, with constructor path string, and args encoded as nested msgpack doc

* Smaller msgpack extension types

* Update lock files

* lock

* Don't delegate to pydantic json

* Fix kafka serde

- should use our serializer to load, as inputs to subgraphs are serialized using it

Nuno CamposandGitHub 66fc7c96aa More performance improvements in checkpointing and channels (#1685) 
* Performance improvements in checkpointer libs

- Use sha1 instead of md5 for hashing (faster in python 3.x)
- Use orjson instead of json for json dumping (sadly can't use for json loading)

* Update tests

* Update

* Use random number instead of hash for get_version_number

* Avoid saving writes for the last task to complete in each step

- only when possible, exceptions for ERROR, INTERRUPT, SEND

* Make Channel.from_checkpoint a regular function

- context manager no longer needed since Context became a managed value

* Use __slots__ for Channels

* Fix for kafka

Nuno CamposandGitHub 95b97d69ec Nc/12sep/perf (#1702) 
* Remove unused fil;e

* Add benchmark-fast command for running locally

* Small improvements to jsonplus serializer

* Don't use PregelNode.mapper when schema is a typed dict

- All it would do is create a new copy of same dict

* Avoid copying checkpoint when fetching at beginning of loop

* Fix needs array

* Update tests

Nuno Campos 9b6100bc4f Avoid storing Sends twice in memory and postgres checkpointers 
- Sends are stored through put_writes, so we don't need to also store them inside checkpoint object
- On reading checkpoint, reconstruct pending_sends from the stored writes
