[appmgr] Implement linear backoff for diagnostics directory waiting.

A component that takes over 15 seconds to startup and serve
out/diagnostics would be missing its diagnostics output. This change
implements non-probabilistic linear backoff up to 30 retries starting at
500ms for each retry, which gives a little under 4 minutes to start up.
