Investigate connection-to-server limit (if any) in node connector, implement if inadequate

[jonvuri]

Limit number of connections to server to around 6 like browsers do in Node mapd-connector, with some task dispatcher such as async.eachLimit. (Possible existing pattern in mapd-client-v2)

[esamuel1]

Adding notes for the fix that helped resolve this:

Add the following line to this file: /lib/systemd/system/mapd_web_server.service?
LimitNOFILE=65536

This needs to go between ExecStart and Restart properties in the file. I After editing the file, you will need to run the below command for the changes to pick up:

sudo systemctl daemon-reload && sudo systemctl restart mapd_web_server
