add --track-logs-interval flag (#2807)

* add --track-logs-interval flag

Signed-off-by: pznamensky <kompastver@gmail.com>

* address review nits: logsInterval plumbing and test coverage

- kubedog: move defaultLogsInterval next to TrackOptions in options.go,
  where the field it defaults lives
- kubedog: pass logsInterval through newProgressPrinter instead of a
  post-construction field assignment; zero falls back to the default
- kubedog: cover WithLogsInterval and the LogsInterval default in
  tracker tests
- config: document that defaultTrackLogsInterval is shared by sync and
  apply and mirrors kubedog's default
- config: add a negative-interval validation test case
