> During cluster creation using a blueprint, the initial INSTALL and START commands are
automatically retried by the agent upon failure. This support was added to allow immediate
scheduling of commands (as soon as hosts join the cluster) rather than waiting for all hosts
to join.
> The feature itself is straight forward - if any command failed then agent will automatically
retry them for a configurable duration.
> Auto retry itself is useful for other commands where user may want some retries before
giving up - e.g. Restart commands. Rather than failing immediately agents can try a few more
times. Its particularly useful if the start of a service depends on another service which
is also being restarted.
