Client query temporarily fails

[ilveroluca]

Occasionally when retrieving a time series through the Client something goes wrong with the connection with TDMq.

Users report first getting an error:

('Connection aborted.', RemoteDisconnected('Remote end closed connection without response'))

Upon retrying right afterwards

HTTPConnectionPool(host='compassionate-fermi-tdmq.default', port=8000): Max retries exceeded with url: /api/v0.0/sources/204bbb85-1f54-54ab-9527-b20511e4528e/timeseries?after=2021-01-07+00%3A00%3A00&before=2021-01-08+00%3A00%3A00 (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f4ffcdae250>: Failed to establish a new connection: [Errno 111] Connection refused'))

After retrying a few times the connection is re-established and the query goes to completion. When successful the query fetches about 20k records. The size of the result set doesn't seem to be a problem since queries of this size by the same user usually work fine.
