Skip build-history recording entirely when history.maxEntries is explicitly set to zero, while still closing progress for normal builds. Cover successful and failed builds across the integration worker matrix and document the configuration. Closes moby#3798.

maxEntries is now a pointer so an omitted value is distinguishable from an explicit zero. Omitting it keeps the previous age-only GC behavior, the default of 50 applies only when the whole history section is absent, and an explicit zero disables recording of new build history. Build metrics no longer depend on history being recorded. The step summary and the error status are shared with the history path, and the solver emits the same completion metrics when history is off. Collection is skipped entirely when no meter provider is configured. Signed-off-by: Tonis Tiigi <tonistiigi@gmail.com>
