spamd

[zeroXbrock]

Motivation

run contender for a long time, or indefinitely.

Solution

New CLI command spamd, accepts same parameters as spam command, with an additional time_limit param. The main difference between spam and spamd is that in spamd, commands::spam is executed in a loop, whereas it's only executed once in spam. The time_limit parameter is optional -- if it's None, spamd will run indefinitely. If it's Some, the spam loop will exit after both the time limit has been exceeded, and the current spam batch is finished processing (so that time limit doesn't prevent us from collecting results).
