[sc-25841] Remove 4MB limit for gRPC message payloads - #49

Currently our logic chunks data to send over gRPC according to numbers of rows of data, this led to large streamsets in the multivalue api erroring out while trying to recv this data on the client side.

This PR sets the limit for the client to receive from the server to be unlimited for the time being. This will allow arbitrarily-sized streamsets to have successful multivalue queries.

In the future we should update our logic to better handle these size limits when sending from the server, but this is a patch fix for now.

I tested this for 5000 streams on ni4ai, with a sampling_frequency of 30 for 100seconds of data, this would error out on the master branch, but successfully returns the data on with this PR.

MWE

import btrdb

conn = btrdb.connect(profile='CLUSTER_WITH_MANY_STREAMS')
streams = conn.streams_in_collection(*conn.list_collections(), is_collection_prefix=False)

end = btrdb.utils.timez.currently_as_ns()
start = end - btrdb.utils.timez.ns_delta(seconds=100)

strm_set = btrdb.stream.StreamSet(streams).filter(start=start, end=end, sampling_frequency=30)

table = strm_set.arrow_values()
