Add a timestamp provider that inherits the timestamp from the parent
In some special setups (e.g. if fragment version should always match host version) it could be useful to inherit the build timestamp from the fragemnt host. This adds a new timestamp provider to allow this use-case by specify <timestampProvider>fragment-host</timestampProvider>.
