Spawn compute

spawn is a low level API used internally by methods such as sink_parquet. It provides the user with maximum control over spawning queries onto remote compute.

spawn(lf, *, dst[, context, partitioned_by, ...])	Spawn a remote query and await it asynchronously.
spawn_blocking(lf, *, dst[, context, ...])	Spawn a remote query and block the thread until the result is ready.
spawn_many(lf, *, dst[, context, engine, ...])	Spawn multiple remote queries and await them asynchronously.
spawn_many_blocking(lf, *, dst[, context, ...])	Spawn multiple remote queries and await them while blocking the thread.
