Implement Configurable Chunk Rate Limiting

[aaronbuchwald]

Nodes produce chunks with a specified amount of claimed resources. When a block is built from a set of chunks, the aggregate must fit below the required block limits.

Chunks should include the fees.Dimensions consumed by the transactions they have included.

When nodes sign chunks received from a chunk builder, they should apply configurable rate limiting that limits the number of chunks/s, bandwidth consumed by the full chunk, and the fees.Dimensions claimed to be included by the transactions within the chunk.
