core: capped exponential backoff for CoCo CommandExecutor

Some commands run by CoCo complete quickly and would benefit from faster
polling; however, some may take longer to complete and polling too often
consumes unnecessary CPU.  This is a good use case for capped
exponential backoff, which is implemented here purely in-memory.

New commands will poll 1 second, doubling until reaching the
AsyncCommandPollingRateInSeconds configuration value.
